>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.
