Workflow schedules support exact run times

Workflow schedules now support precise fixed-time runs and recover better when scheduled work is picked up slightly late.

• Choose exact schedule times beyond standard quarter-hour options.

• Ask the AI workflow assistant to create schedules at exact times.

• Run fixed schedules in the configured time zone.

• Catch recently due runs without starting duplicate runs for the same scheduled minute.

• Keep disabled schedule triggers from starting workflow runs.
