The question has already been well-answered, but since I've found using the datetime module to be tough going, I was wondering if either of these would be easier to understand and use: 1. http://www.egenix.com/products/python/mxBase/mxDateTime/ I see that mxDateTime comes with a 55-page manual as a PDF. 2. http://labix.org/python-dateutil Dick Moores -- http://mail.python.org/mailman/listinfo/python-list

Thank You Dominic -- http://mail.python.org/mailman/listinfo/python-list The easiest way I have found, is to use epoch, subtract the length of time, then convert back to whatever format. 24 hours is 86400 seconds. import time time.localtime() (2007, 8, 16, 9, 41, 28, 3, 228, 1) time.localtime(time.time() - 86400) (2007, 8, 15, 9, 41, 21, 2, 227, 1) -- http://mail.python.org/mailman/listinfo/python-list

Or use a timedelta.

yesterday.strftime('%m%d%Y')

The C library mktime function is documented to fix up out of range values,. For example July 32 becomes August 1 and August -1 becomes July 31. Python presumably inherits this very useful (and seemingly not well known) behavior, but it is not documented. Is this just an oversight, or is it intentional on the grounds that it might be platform-dependent?

Freeze problem(second time do not imported)
Hi, I am using DLLs from freez.py and these dll are running inside a program(Not OS level). If I have 2 dlls such as A.dll, B.dll, I can import and run a(A.run()) function in A.dl, next I can import and run a function(B.run()) in B.dll Next if I try to run A.run(), it doesn't work at all.

Problem with time
Hi, i have a problem with time in python. 1) i got 2 values from mysql db (fields are time type) 2) python get it as type 'datetime.timedelta' (why timedelta???) 3) i need to compare 2 fields with actual time ... EG: if ArrOutputsAuto[i].TimeFrom = GNow and ArrOutputsAuto[i].TimeTo = GNow: i need actual time, and 2 fields from DB in datetime.time type (correct me if i'm wrong) so i can do my test if time= ... I think i can grab time from DB in string and parse it in datetime.time(x,x,x) but its not very optimized Any idea ? Thanks -- http://mail.python.org/mailman/listinfo/python-list

problem with time
Hello, I'm writing a small program that needs to check Unix timestamps for falling into an interval (typical usage: ./program 2005-03, you get the idea). Now, I create two time stamps from the user's input to create the interval's borders using mktime(). Trying to check the sanity of my program, I also converted the values back to tuples using localtime(). Unfortunately, I get back one of them with the DST flag set, and the other with the DST flag unset. I have _no_ idea on how localtime() could reasonably synthesize different values for that flag for _any_ time value converted in about the same millisecond. What gives?
