from: http://stackoverflow.com/questions/12081310/python-module-to-change-system-date-and-time
can we not make use of datetime.datetime.time() function to set system date..?
ReplyDeleteand i see that it works fine independent of platform.
Hi, thanks for the comment.
DeleteI haven't looked at this for a while as I found I did not need this any more but...
As you have noticed I was trying to make sure it worked in Linux and Windows, and I think the behaviour of datetime.datetime.time() was not consistent across both platforms.
