Like for example, I have a date: "13th March 2011, 22:34.5" and today's date is "22 March 2012 3:17.16"

How can I compare the dates and check whether the date is older or newer?

Well best thing you can do is: use getdate(); for this.
So you save for example:

Код:

new date1;
date1 = getdate();

and next week you check

Код:

new date2;
date2 = getdate();
if(date2 > date1) //then is date1 older .

compare each value in a decreasing order: year, month, day, hour, minute, second. when any comparison returns a difference, the date is (depends on how you check it, > or <) bigger.
are all date strings formatted the same way? yours looks like

pawn Код:

format(datestring,sizeof(datestring),"%dth %s %d, %d:%d,%d",day,monthname[month],year,hour,minute,second);

so by using

pawn Код:

sscanf(datestring,"d' 's[16]' 'd','d':'d'.'d",day,month,year,hour,minute,second)

and reordering the comparisons (years before months), it should work

Thats also possible, but it's much more work then the way I explain. But yea if you wan't you can use babul's way.

one issue using my method, is the need of converting the month string into a number ("march"=3) for easier comparing, which is not that easy for strings. if all date informations are stored as numerical values, its a piece of cake

[Roel]

Yep, but you can store all date informations in numerical right?
Only if a player has to input the date by hisself you cannot use my option.
Anyway we will see what he uses :P

mktime: Get the timestamp from date.

getdate: Get the actual timestamp

Due to timezone, maybe is need to decrease/increase the mktime timestamp in some hours.

Be aware that on the 31th of December 'getdate()' returns something like 365, but on the 1st of January, it returns 0 or 1 again. So it's safe, as long as the dates aren't around New Year. Maybe it's useful to compare the years too.

I made a fairly decent guide explaining Unix Timestamps a while ago, this might not be what you want, but this is the most effective way of dealing with dates.

Thanks everyone, all your information were useful. I've overcome this problem.
