YEAR, MONTH and DAY functions calculate as if the Gregorian calendar is in use, the DATE functions returns an error, and implicit conversions (like done by formatting the serial number as date) is local, epoch dependent.

It is up to the user to decide whether a function is usable for his use case.

But we should extend the help about the use of Gregorian calendar so that the user can know about the behavior.

Excuse me ... I did not catch everything you wrote ! :(

Could you explain better please ?


In my point of view, no function should return a wrong value, in any case. If there is a range of date the function return a right value, out of the range should raise an error condition. Other way it is a bug.

day, month and year functions return a wrong value for "1482-12-30" ... it should return a right value or an error message.

Or rather, of bug 144692 - and they all have a common bug 144699, which needs ODF clarification to be resolved.
