Category: None Group: None Status: Open >Resolution: Rejected Priority: 5 Private: No Submitted By: David Fraser (davidfraser) Assigned to: Roger Upole (rupole) Summary: Allow conversion of PyTime to datetime.datetime Initial Comment: It would be great if you could convert PyTimes directly to datetime objects. It would be even nicer if they *were* datetime objects, but that's a big change... ---------------------------------------------------------------------- >Comment By: Vernon Cole (kf7xm) Date: 2010-05-03 01:55 Message: The capability to convert PyTimes to datetime already exists:... >>> import adodbapi >>> tc = adodbapi.pythonDateTimeConverter() >>> d = tc.DateObjectFromCOMDate(37435.7604282) >>> d datetime.datetime(2002, 6, 28, 18, 15, 0, 996480) ---------------------------------------------------------------------- Comment By: Roger Upole (rupole) Date: 2008-10-31 10:51 Message: I'm currently working on allowing datetime.datetime objects to be used in place of PyTime. I've also run into the issue noted in bug #2209864 with fractional second truncation when converting variant DATEs. There's also a large performance hit, since PyTime stores the value internally as a DATE (really a double), meaning it doesn't have to be converted back to a float. However, passing a datetime to/from COM becomes really expensive, since it will have to be converted not only on output, but each and every time it's passed to a function that needs a DATE. I'm considering trying to subclass datedate.datetime so we can also store the variant DATE with it, but haven't looked at it too deeply yet. In Python 2.3 datetime is pure python, but in 2.4 and up it's a builtin implemented in C, which may or may not support subclassing.
