Maybe you need to get out more. :-) This is how datetime is represented in App Engine's datastore: https://developers.google.com/appengine/docs/python/datastore/typesandpropertyclasses#DateTimeProperty (Note: These docs are unclear about whether a tzinfo attribute is present. The code is clear that it isn't.)

From the docs: "Some libraries use the TZ environment variable to control the time zone applied to date-time values. App Engine sets this environment variable to 'UTC'." This means that App Engine's local timezone is UTC and strictly speaking this is not a counter example to what I said. Proposed mktime() based code will still work in this case.
