Expiring PGP key expire date is shown as "1970-01-01 00:00"

trident 1.4.5

Uploaded public PGP key (.asc) with a 10 year expiration. The expires date is displayed as 1970-01-01 00:00

Sounds like from #115 this is expected for non-expiring keys, but it also shows on expiring keys.

That is as the current code is not properly parsing the expiry dates, setting them to 1970-01-01 (0).... fix is en route....
