Simple sleep task taking longer than expected

Help

I have a simple task that sleeps for a configured amount of time:

class SuspendConfig(BaseModel):
    h: int = 0  # hours
    m: int = 0  # minutes
    s: int = 0  # seconds

@task
def suspend(config: SuspendConfig):
    total_wait = (config.h * 3600) + (config.m * 60) + config.s
    print(f"waiting for {total_wait} seconds")
    time.sleep(total_wait)

However, this task often takes far longer when called in a flow:

09:56:57.257 | INFO    | Task run 'suspend-0' - waiting for 900 seconds
11:21:27.748 | INFO    | Task run 'suspend-0' - Finished in state Completed()

Any ideas as to why? The total time that the task runs doesn’t seem very correlated to the time I configure it to sleep for. I’ve read that there can be some variability in time.sleep(), but this seems like a lot. Is there a better way to add delays between tasks?

Thanks!
