that's got the right number of zeros to
be a date expressed as microseconds since epoch
in which case the magic spell is
select 'epoch'::timestamptz
+ '1s'::interval
* (616962528000000000::bigint /1000000000.0);
gives me a date in 1989
if it's some from a microsoft inspored system instead of AT&T inspired
you might need to add '10 years'::interval to the result.

except the code which produces a likely data treats it as nanoseconds....
