UPDATE: This issue has been resolved for FME Server 2022.2 b22729 and newer.
Hi @ngstoke
I'm sorry that you have encountered this issue, I have been able to reproduce it and have filed a report with our development team to request a fix (issue ID: FMESERVER-18922). It looks like if FME Server is hosted in a different time zone when creating a Basic or CRON Schedule the start and end times are adjusted.
For example, if my current Server time: Fri-02-Sep-2022 11:30:00 AM -0700 and I set my schedule to start at 2022-09-02 20:00. After saving the Schedule it becomes 2022-09-02 13:00.
In FME Server 2021.2.6 this problem will occur in Schedules created from the Schedules page or from within an Automation.
In FME Server 2022.1+ this problem will occur in Schedules created from within an Automation only.
To workaround this issue, please set the Schedule Type to Repeat on Interval instead. I'm sorry for any inconvenience this may cause!
