Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hello all,

I've just been testing a bit of code associated with timekeeping.

One test I have done is to set the date$ and time$ to just before midnight at various month ends and leap years and non-leap years, with the following results:

All non February months in leap years and non leap years roll over correctly from the end of one month to the next, updating the year as necessary.

February in a leap year rolls over from 29-02-YYYY to 30-02-YYYY, so I think this is a bug.

Should I submit this to the official support page?Edited by AndrewB 2012-02-15

Damn, I hate it when bugs turn up.
Thanks folks, I will fix it in 3.2 (but probably too late for this leap day).

Yep, no problem - I'll check for it in my code and cope with it that way.

Cheers.

I think I may have also found a bug in the 'shorthand' Print statement.
Print @(10,10)"hello" = ok
? @(10,10)"hello" = error
