Modified xldate_as_tuple() to return microseconds.

Return microseconds from xldate_as_tuple() for additional
compatibility with datetime and pandas. Issue #76

Hi Chris,

I suspect there's a lot of code out there that assumes that tuple will be of the current length.

That is a fair point.

a separate function (maybe xldate_as_extended_tuple()?), although I suspect you'd end up with a big chunk of duplicate code for speed reasons

That is a reasonable possibility. To avoid duplication, xldate_as_tuple() could be a wrapper around xldate_as_extended_tuple(). However, as you say this would introduce a performance overhead.

If you fancy a bigger challenge, it would be great to have an option to open_workbook, say, open_workbook(..., datetime=True) that would result in the value of the cell being as real datetime object rather than a float

Which lead us to this logical conclusion. :-)

I'd be willing to try implement a xldate_as_datetime() function (with testcases and 1904 epoch support) that returned a datetime.datetime object from an excel serial date/time. If the performance of that is reasonable you can decide if it is worth wiring up to the cell object.

I'll put it on a separate branch/PR and you can close this one if you want.

Regards,

John

Ah, penny dropped.

Yes, xldate_as_datetime(xldate, datemode) would be great, and yes, probably done in a separate branch.
I'll close this one off for now.
