Hi tabbiati,

Check these terms in the dictionary:
convert
dateitems
seconds
I am sure they will supply a solution to your problem!
And of course ask here if you get stuck!

Hi Tabbiati.
I need to compare date/time too because I am programming something like scheduler/organizer and it's necessary to check if current datetime is > than deadline of event
Which format of date time it's better to use?
I think to convert to seconds and after compare, can be good idea? Can I know how you solved?
thanks

Yes that's the way to go.
Code: Select all
put the date into tNow
convert tNow to seconds
put "1/1/11" into tOldDate
convert tOldDate to seconds
if tNow > tOldDate then answer "After"

Great, but how to let know to LiveCode if the first item of tOldDate is a mont or a day?

Hi.
In the United States, where we assume that everyone speaks English and uses our date and time format, the month would come first, then the day, then the year. I have heard that people do not always follow this format, which we cannot understand.
Anyway, look up the "useSystemDate" in the dictionary. It will point you in the direction of taking control of that format.

Thank you so much for the replay dunbarx, what I have forget to mention is that I would like to use a date to calculate the expiration time of a beta version, so I have to be certain that LiveCode understands that that date is passed whenever the user use it. So if somebody have more info to implement a unique "universal" date, I will be happy.
PS
Thank you for the useSystemDate tip, I will go to read the documentation.

Hi.
Well, if you use the seconds, which is format independent, you are done. All you need are a few custom functions to do the comparisons and date translations.
Is the internet date also platform and format independent?

OK, so I learnt that the useSystemDate specifies whether the date and time functions should be formatted in accordance with the user's system preferences, or in the standard format used in the United States. The default value is "false", so I guess that if I hard-code a date, it will be valid for the whole world.
