Rounding time in Python

Question

What would be an elegant, efficient and Pythonic way to perform a h/m/s rounding operation on time related types in Python with control over the rounding resolution?

My guess is that it would require a time modulo operation. Illustrative examples:

• 20:11:13 % (10 seconds) => (3 seconds)
• 20:11:13 % (10 minutes) => (1 minutes and 13 seconds)

Relevant time related types I can think of:

• datetime.datetime \ datetime.time
• struct_time

Answer 1

For a datetime.datetime rounding, see this function: https://stackoverflow.com/a/10854034/1431079

Sample of use:

print roundTime(datetime.datetime(2012,12,31,23,44,59,1234),roundTo=60*60) 2013-01-01 00:00:00
