Calculates the difference between two times in hundredths of a second.
Example
// Affiche le temps écoulé depuis 12h15
Diff is int 
Signe_temps is string
MonRésultat is string 

Diff = TimeDifference("1215", TimeSys())
MonRésultat = IntegerToTime(Abs(Diff))
IF Diff < 0 THEN Signe_temps = "-"
Info("Temps écoulé : " + Signe_temps + Left(MonRésultat, 2) + " heures " + ...
	Middle(MonRésultat, 3, 2) + " minutes " + ...
	Middle(MonRésultat, 5, 2) + " secondes " + ...
	Middle(MonRésultat, 7, 2) + " centièmes de seconde")
Syntax
<Result> = TimeDifference(<Start time> , <End time>)
<Result>: Integer
Number of hundredths of a second elapsed between the two times. This number is the result of the following operation:
<End time> - <Start time>.
The result is negative if <Start time> is after <End time>.
<Start time>: Character string or Time variable
Start time in the following format:
  • HHMMSSCC
  • HHMMSS
  • HHMM
  • HH
<End time>: Character string or Time variable
End time in the following format:
  • HHMMSSCC
  • HHMMSS
  • HHMM
  • HH
Remarks

Format of result

To get the duration in another format (HHMMSSCC for example), use IntegerToTime.
