how to extract up to the minute component of a unix timestamp?

I have a list of POSIX timestamps such as 1331567982 that I process using datetime.utcfromtimestamp which gives me a date format like: year - month - day - hour - minute - seconds.

However, for resampling purposes I just need to extract the timestamp up to the minute precision, that is year - month - day - hour - minute, but no seconds.

How can I do that using functions from the datetime module only (no Pandas)?
