Fixed: Releases from PTP showing skewed publish date

PTP returns UTC timestamps, without a timezone specifier. Previously, users
would see skewed publish dates, as the UTC timestamps were being parsed
as if they were in the system's timezone. To fix this, we just assume the
publish date is in UTC.
