Re: Extended date and time

Hi - I need to add support to a program for dates and times. The built-in
Python library seems to be okay for many purposes, but what I would like
would be Unix epoch style times (seconds relative to some date), covering a
large period from the past to the future. What would be nice would be a
library which can take floating point seconds from an epoch.

Does anyone know of a library which can convert from human style dates and
times to a floating point epoch and back again? I expect I could fudge the
fractional seconds with the built-in library, but I can't see how to get
dates in the past.

Thanks, Jeremy.

Have you looked at mx.DateTime:
http://www.egenix.com/products/python/mxBase/mxDateTime/

In matplotlib, I also use their Dates modules functions for
conversions (see the near bottom of the page):
http://matplotlib.sourceforge.net/matplotlib.dates.html

In the scipy sandbox, you can also build a package called
'TimeSeries':
http://www.scipy.org/SciPyPackages/TimeSeries

I also have trouble with date/times with whats available. Off the top
of my head... converting a numpy array of epochs to some datetime
object and back.

If I had the time I'd contribute additional functionality to Pierre's
and Matt's TimeSeries module (the one in scipy).
