schedule every minute schedules every 61 seconds

[microprediction]

Scheduling every minute leads to drift. The job is called at 36 seconds past the hour, then 37, then 38 and so forth.

Is this caused by your delay?
For example...

schedule.every().minute.do(job)
while True:
  try:
    schedule.run_pending() # 60 Seconds
    time.sleep(1)                   # 1 Second
  except KeyboardInterrupt:
    break

Perhaps use schedule.idle_seconds()

schedule.every().minute.do(job)
while True:
  try:
    schedule.run_pending()
    time.sleep(schedule.idle_seconds())
  except KeyboardInterrupt:
    break

This worked fine:

while True:
  schedule.run_pending()
  time.sleep(max((schedule.idle_seconds() - 1),0))

Hello, the solution helped in reducing drifts, but it seems the scheduler didn't took the function run-time into consideration (my function was I/O bound, took 0.7-0.8 s) and still caused drifts

Am I correct about that?
