lol, 64bit integer overflows are fun to debug

Browse Source 
specially when running a multi-arch cluster and HA with poor observability. a `time.Duration` was being casted to an `int` (because I clearly have no clue of what I'm doing). All is well on 64-bit processors, but 32-bit processors choke on the very long micro-second precision int, overflow, and turn `7d`, around `604800` seconds into `-114753536` seconds, which the browser happily (and correctly) turns into a cookie sent to /dev/null. lol.
