How to use TTimeStamp function?

Hi...how do you use the TTimestamp type? What it says in the online help doesn't explain a thing! I keep getting a value of 0 in both the date field and time field. All I want to do is display to the user how long my program takes to run in seconds. Basically, I want to have a "begintime" value when my process starts running, then an "endtime" value when it's done. Then subtract begintime from endtime to get the elapsed time in seconds...nothing complicated.

Cheers

Hi aztec,

You can do it with this :
var ElapsedTime : TDateTime;

Begin
 ElapsedTime := Now;
 // compiling
 ElapsedTime := ElapsedTime - Now;
 ShowMessage('Elapsed time between compiling : '+TimeToStr(ElapsedTime));
End.

Regards, Zif.

But won't the TdateTime function just give me elapsed time in days and fractions of days? Like 0.065 days or something like that? That's no good, I need something that'll show seconds and fractions of seconds.

Any suggestions?

Nope, TDateTime is splitted in a date and time part. (doubles)

Delphi stores date and time values in the TDateTime type. The integral part of a TDateTime value is the number of days that have passed since 12/30/1899. The fractional part of a TDateTime value is the time of day.


So when you put
ElapsedTime := Now ( the hours, minutes, seconds, month, year  will be filled in in the TDateTime)
If you use Time : Only hours, minutes, seconds will be filled in
By Date : only month year and day will be filled in

Usind TimeToStr will give the hour in a certain format.
