Description
Timestamps for
created_atandupdated_atare hardcoded to US/Pacific, which produces incorrect dates for non-Pacific users and breaks date-range filtering (especially near UTC midnight). This replaces allpytz.timezone("US/Pacific")references with stdlibdatetime.timezone.utcand removes the unusedpytzimports.Fixes #4402
Type of change
Please delete options that are not relevant.
How Has This Been Tested?
Exiting tests pass. The change is a straightforward timezone constant swap with no logic changes.
