[Pythonmac-SIG] time screwed up

Hmmm, it looks like the current Mac time routines (at least the ones used
by Python) use 1900 as the epoch (look at your compiler's time.h for
confirmation), while the apple event system uses 1904 (which my brain says
is the start date that was used by the time routines a long time ago).
Trying the script

0 as date

in the script editor returns

date "Friday, 1 January 1904 12:00:00 AM"

which seems to confirm this.

>>> print asctime(localtime(4*365*24*3600))   # no leap years - whew!
Fri Jan  1 00:00:00 1904

It seems as though the conversion routine to convert a longDateType should be:

if t == typeLongDate:
	a, b = struct.unpack('lL', desc.data)
	return (long(a) << 32) + b + 126144000

The recently modified source for aepack.py should probably be updated to
account for this.
