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.
