Narrative:

Our watch and the FSS (on field) clock differed by 1 min. We rolled (for takeoff) at XA09:30 by my watch. FSS said time was XA10:30. Clearance void time was XA10:00. No conflicts. Reported in with approach control normally and proceeded to our destination (atl). Should have verified my watch against FSS clock.
