# computing difference between 2 times

## computing difference between 2 times

(OP)
Hi. how do I compute the difference between two times? In the result, I want to see the hour difference and minute difference as HH:MM, not just the hour or minute. the time1 and time2 are formatted 'YYYY-MM-DD HH:MM:mm.ss'. I only want the HH:MM part from the computed difference. Thank you.

### RE: computing difference between 2 times

Try the SecondsAfter function, it gets the number of seconds one time occurs after another. Syntax :

SecondsAfter ( time1, time2 )

Then just devide by 60 for minutes and 60 again for hours... hope this helps

### RE: computing difference between 2 times

Hi,

Your solution to your problem is to use the SecondsAfter() function. It returns a long value of seconds being the difference between the two time values. To conver this value to a time format, just use the String() function to format the computation:

//////////////////////////////////////////////////////////
time   lt_Time1, lt_Time2 ;
long   ll_Secs ;
string ls_Diff ;
//
ll_Secs = SecondsAfter( lt_Time1, lt_Time2 ) ;
//
ls_Diff = String(( ll_Secs / 60 ) / 60 ) + ":" + String( ll_Secs / 60 )
//////////////////////////////////////////////////////////

Hope this helps...

Hi Peglin,

I hate to offer any code that is not from a real-world situation. The above code I posted yesterday does have some glitches. However, you have posted the same question onto another group and I posted a bug-free solution out there. Just surf to:
