Python Time Offset

How can I apply an offset on the current time in python? In other terms, be able to get the current time minus x hours and/or minus m minutes and/or minus s secondes and/or minus

Solution 1:

Use a datetime.datetime(), then add or subtract datetime.timedelta() instances.

>>>import datetime>>>t = datetime.datetime.now()>>>t - datetime.timedelta(hours=1, minutes=10)
datetime.datetime(2012, 12, 26, 17, 18, 52, 167840)

timedelta() arithmetic is not supported for datetime.time() objects; if you need to use offsets from an existing datetime.time() object, just use datetime.datetime.combine() to form a datetime.datetime() instance, do your calculations, and 'extract' the time again with the .time() method:

>>>t = datetime.time(1, 2)>>>dt = datetime.datetime.combine(datetime.date.today(), t)>>>dt
datetime.datetime(2012, 12, 26, 1, 2)
>>>dt -= datetime.timedelta(hours=5)>>>dt.time()
datetime.time(20, 2)
