The max duration of a recording with INTEGER is less than 600h. It's certainly not out of possibility that a recording longer than 600h will be created, so we might want to consider moving to BIGINT to be safer.

When adding a long reecording MB crashed.

(1) extremely long recording but MB should accept it (because it’s real) - bug

(2) long >eg. 99 minutes should be flagged for edit voting - enhancement

(3) ends in the future (ideally show changing date/clock!) - warn/flag - enhancement
