The datetime module is not restricted to 1970...2038. It allows years 1...9999 (it uses the Gregorian calendar even before its adoption). >>> import datetime >>> datetime.MINYEAR, datetime.MAXYEAR (1, 9999) >>> datetime.date(1500, 2, 29) Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: day is out of range for month >>> datetime.date(1600, 2, 29) datetime.date(1600, 2, 29) The range allowed by the time module is probably implementation dependent. I can do things like >>> time.gmtime(-11670998400) time.struct_time(tm_year=1600, tm_mon=2, tm_mday=29, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=1, tm_yday=60, tm_isdst=0) >>> time.gmtime(2**55) time.struct_time(tm_year=1141709097, tm_mon=6, tm_mday=13, tm_hour=6, tm_min=26, tm_sec=8, tm_wday=6, tm_yday=164, tm_isdst=0) >>> time.gmtime(2**56) Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: (75, 'Value too large for defined data type') Peter _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
