Hi @<1523701205467926528:profile|AgitatedDove14> , Thanks for rresponse!
this my simple code to test scheduler

import datetime
from clearml.automation import TaskScheduler
  
def test_make():
    print('test running', datetime.datetime.now())

if __name__ == '__main__':
    task_scheduler = TaskScheduler(
        sync_frequency_minutes=30,
        force_create_task_name='controller_feedback',
        force_create_task_project='Automation/Controller',
    )

    print('\n[utc_timestamp]:',datetime.datetime.utcnow())
    print()
    task_scheduler.add_task(
        target_project='Automation/testing',
        name='fetch feedback',
        schedule_function=test_make,
        minute=35, hour=4, day=1,
        recurring=True,
    )

    print(task_scheduler.get_scheduled_tasks())

    task_scheduler.start()

and the console output like this after pass the 4.35 utc time, there is no job running.
