This file
http://freeman2.com/saytime2.htm
was written in Chinese first. Document 1 was in
Chinese. English version has document 2 and 3.
Document 2 use hidden box  to store begin/end time.
Document 3 use js variable to store begin/end time.
Since hidden box is external to Javascript, so
hidden box method is slower.
Freeman is not a programming expert, learn from
experiment/error. When write document 2, I am not
sure if global variable defined at file beginning
is still valid at file end. Since in between,
browser load text and picture. Javascript stopped
during this period.
On 2007-10-03-19-46 do experiment, use variables
   and discard hidden box.
On 2007-10-03-19-50 confirmed variables work.

This version should be a little bit faster.

If you want to use elpase code in your web page,
please do as following:

1. create a set of variables
var elap1end,elap1bgn;
   to record begin/end time.
   Because the time difference equation is
   elap1end-elap1bgn
   so I use elap1end,elap1bgn;
   not  use elap1bgn,elap1end;

2. write code to record beginning time
   save time to variable "elap1bgn"

elap1bgn //9610032043 time label is for search
=saytime(203);

3. elapse time required code follows immediately

   your code is here.

4. write code to store end time to variable
   "elap1end" 

elap1end=saytime(203); //9610032046 time label is for search

5. calculate time difference

document.write(
'<br><font color=red>run first codes elapse time is '
+(elap1end-elap1bgn)/1000
+' seconds<br></font>');

The  end  time has larger  number,
The begin time has smaller number,
Above 'elap1bgn' and 'elap1end' can be
other name. But must be consistent.

If you have second group code need to observe,
create another set variables, change '1' to '2'
'elap2bgn' and 'elap2end' must enclose the
observed codes.

Your file should have next two function
definitions
function getdigit(inDigit){.....}
function saytime(type0){.....}
They must be defined before use. It is better
to define function in <head>

(elap1end-elap1bgn) get milliseconds

(elap1end-elap1bgn)/1000 change to seconds.

This file use four set elapse time measurements.

1. whole file load time
   Beginning time record
elap1bgn //9610032043
=saytime(203)
;
   ending time record
elap1end=saytime(203); //9610032046

after run, two variables has value like
elap1bgn=1191525755328 page start
elap1end=1191525755593 page done
above long digits is from Chinese version.
English version should have shorter elapse
time. Since English version has less task.

To report the elapse result, use next code
document.write(
'<br><font color=red>Load this file, elapse time: '
+(elap1end-elap1bgn)/1000
+' seconds.<br>Seconds is the answer of "wait how long".<br>'
+'Picture load is not counted.</font> 9609132023<br>'
);

2. second set elapse code is announcement header code 
   that is rocsitee.js

   to record start time
<SCRIPT language=JavaScript>
elap5bgn=saytime2(203);  //9610032138
</SCRIPT>

   to run announcement header code
<script src=
http://freeman2.com/rocsitee.js
> </script><!--9610011318 add-->

   to record end time
<SCRIPT language=JavaScript>
elap5end=saytime2(203);  //9610032139
</SCRIPT>

   to calculate and report the result
document.write(
'<font color=red>To run announcement header code elapse time is '
+(elap5end-elap5bgn)/1000
+' seconds<br></font>');

3. third set elapse code is to measure ten
   Miss Deng's picture code elapse time

   to record start time
<SCRIPT language=JavaScript><!--
elap2bgn //9610032054
=saytime2(203);
//--></SCRIPT>

there are about 70 lines picture display code.

   to record end time
<SCRIPT language=JavaScript><!--
elap2end //9610032055
=saytime2(203);
//--></SCRIPT>

   to calculate and report the result
document.write(
'<font color=red>To run ten Miss Deng's picture code elapse time is '
+(elap2end-elap2bgn)/1000
+' seconds<br></font>');

4. mouse pointer cross Miss Deng's picture elapse time.
  
   to record start time
 onmouseover='elap3bgn=saytime2(203);'

   to record end time
 onmouseout='getelapse(10)'
   this command call function 'getelapse(10)'
   with parameter '10' which indicate mouse
   pointer crossed picture number ten.
   in 'getelapse(10)' record the end time
   as following.
function getelapse(type0)
{
elap3end=saytime2(203); //9610032121
.....
}

   to calculate and report the result
document.getElementById("dengljun").innerHTML=
 '<font color=red>You have touched Miss Deng picture '
+number0[type0]
+' for '
+(elap3end-elap3bgn)/1000
+' seconds.<br>';

Except the mouse pointer movement report, all other
three elapse time is reported at the end of file.

This program
http://freeman2.com/saytime2.htm
record an event start time and end time, then
find out the elapse time in seconds.

Do as following:

1. create a space_1a to record event1 start time
<input type="hidden" id="record01Bgn"
 value=""></input>

2. write command to store start time to space_1a
<SCRIPT language=JavaScript><!--
document.getElementById("record01Bgn").value
=saytime2(203);
//--></SCRIPT>

3. event1 code follows immediately

your code here.

4. create a space_1b to record event1 end time
<input type="hidden" id="record01End"
 value=""></input>

5. write command to store end time to space_1b
<SCRIPT language=JavaScript><!--
document.getElementById("record01End").value
=saytime2(203);
//--></SCRIPT>

6. report the elapse time
<SCRIPT language=JavaScript><!--
var end01=document.getElementById("record01End").value;
var bgn01=document.getElementById("record01Bgn").value;
document.write(
'<br><font color=red>To run event1 code elapse time is '
+(end01-bgn01)/1000
+' seconds<br></font>');
//--></SCRIPT>

Above string 'record01Bgn' can be changed, but must be
consistent.
Above string 'record01End' can be changed, but must be
consistent.

For event two, repeat above code, and change '01' to '02'
'02Bgn' and '02End' must enclose event two codes.

Web page must include code for next two functions
function getdigit(inDigit){.....}
function saytime2(type0){.....}
and they must be defined before using.
It is better to put function definition in <head>.

2007-10-01-11-11 here

(end01-bgn01) is in milliseconds

(end01-bgn01)/1000 is in seconds

document.getElementById("record01End").value
=saytime2(203);

parameter 203
2 indicate return to calling function, let
  calling function calculate time difference.
  not write to current web page.
0 indicate round to seconds
  ten's 1 indicate include milliseconds
  but for one's 3, ten's digit is ignored.
3 indicate report with milliseconds
  since 1980-01-01-00-00
  a sample number is 1189739382437

In this application, use 203 only.

This file used three set of elapse measurements
1. The whole file load time
   start time_1 recorded at next hidden box
<input type="hidden" id="DateString" value=""></input>
   start time_1 recorded at next command
document.getElementById("DateString").value=saytime2(203)
   start time_1 retrieved at next command
var bgn0=document.getElementById("DateString").value;
   end time assigned at next command
var end0=saytime2(203); //9609132020
   calculation and report is done at '+(end0-bgn0)/1000'
   above time stamp '9609132023'
   The whole file load time elapse seconds did not
   use hidden box for end time. Because calculation
   and report is done immediately.

2. Small piece code -- ten marquee pictures -- is monitored. 
   start time_2 recorded at next hidden box
<input type="hidden" id="record01Bgn" value=""></input>
   start time_2 recorded at next command
document.getElementById("record01Bgn").value=saytime2(203);
   start time_2 retrieved at next command
var bgn01=document.getElementById("record01Bgn").value;
   end time_2 recorded at next hidden box
<input type="hidden" id="record01End" value=""></input>
   end time_2 recorded at next command
document.getElementById("record01End").value=saytime2(203);
   end time_2 retrieved at next command
var end01=document.getElementById("record01End").value;
   calculation and report is done at '+(end01-bgn01)/1000'
   which is just below the string "To run ten Miss Deng" .....
   The ten marquee pictures elapse time DOES
   use hidden box for end time. It is
<input type="hidden" id="record01End" value=""></input>
   Because calculation and report can be done any where
   after the end timing.

3. Mouse pointer cross Deng's picture elapse time.
   start time_3 recorded at next hidden box
<input type="hidden" id="timeString" value=""></input>
   start time_3 recorded at next command
 onmouseover='elap3bgn=saytime2(203);'
   start time_3 retrieved at next command
var bgn1=document.getElementById("timeString").value;
   end time_3 did NOT use hidden box
   because calculation and report is done immediately.
   end time_3 activated at next command
 onmouseout='getelapse(1)'
   end time_3 retrieved at next command
var end1=saytime2(203);
   calculation is done at '+(end1-bgn1)/1000'
   just before time stamp '9609302057'

Freeman created 100 Miss Teng pictures,
all use '.tw/'. I did not save before-add-text
pictures. That is I can not erase '.tw/' and
keep picture in perfect condition. I have to
delete all 100 Miss Teng pictures. You can
