I currently have a C# worker console project to which I have to assign to several threads the facility to run at specific times. With IScheduledEventConfiguration and the Cron() method I have used the expression * 13 * * * * which according to crontab.guru should run my process every 1 minute as long as it is 13 hours of the day, but it does not run at all; but if I put * * * * * * * * it works perfectly every minute.

this my code in Program.cs

 host.Services.UseScheduler(
     scheduler =>
foreach (var worker in workers)
{
    if (!(worker.Enabled ?? false)) continue;
    scheduler.OnWorker(worker.Name);
    IScheduleInterval schedulerSyncService;

    switch (worker.Profile!.ParseMode)
    {
        default:
            SyncEmpWorker.AddIsActive(worker.Name!);
            schedulerSyncService = scheduler.ScheduleWithParams<SyncEmpWorker>(worker);
            break;
    }

    var schedule = ScheduleManager.ScheduleFormat(worker.Schedule ?? string.Empty);
    var _schedulerSyncService =
        schedulerSyncService.Cron(schedule);
    if (worker.RunOnceAtStart ?? false)
        _schedulerSyncService.RunOnceAtStart();
}

I have tried using several expressions and looking for other methods including installing several nugets to solve the problem, but the time still does not work.
