Calculating in time

[asdofasdas 0]

So let's say I have a time string like '23.05.2011 11:39' (or what's the best format they come in). How can I add 33 hours and 33 minutes to this string? And then how do I compare these strings, which is bigger/larger/later?

Just looking for some direction to know which functions to work with. Thank you!

Hi,

take a look at _DateAdd and _DateDiff in the helpfile.

Example:

#include <date.au3>
$olddate = '2011/05/23 11:39' ; As it has to have the format YYYY/MM/DD HH:MM:SS
$newdate = _DateAdd("n", 33 * 60 + 33, $olddate)
$difdate = _DateDiff($newdate, $olddate)

Edit: added forgotten include.

MM/DD/YYYY is a terrible format for date strings as they don't sort correctly and most library calls you find around (AutoIt or not) will require ISO 8601 or a compatible subset of (like YYYY-MM-DD) for dates/times in string format. Changing the separator slash from/to hyphen is straightforward.

Formats significantly departing from ISO8601 should be only used for user display but never for storage or computation.
