I have a question with the

IntervalClock

scheduler. If i were to pass

interval=timedelta(hours=1)

to schedule a run for every hour, would this be scheduled to occur at the beginning of every hour? Or would it be relative to when I register the Flow? eg if I register the flow at 1:13pm then the

IntervalClock

would trigger at 13 minutes past the hour every hour? Or would it just kick off at the first minute of every hour?

it would be relative to the start date you set, e,g.

from datetime import time, timedelta
import pendulum
from prefect.schedules import Schedule
from prefect.schedules.clocks import IntervalClock
from prefect.schedules.filters import between_times, is_weekday

clock = IntervalClock(
    start_date=pendulum.datetime(2022, 5, 12, 9, 0, tz="Europe/London"),
    interval=timedelta(hours=1),
)
schedule = Schedule(clocks=[clock])

for sched in schedule.next(20):
    print(sched)
