I have an Ignition project with several Gateway scheduled scripts configured, one of which is set to execute at 11pm (23rd Hour) every day. This project hasn't been changed in a few months and all of the scheduled scripts would execute without issue.
However, since March 9th, all of the gateway scheduled scripts have not executed whatsoever. March 9th also happens to be when Daylight savings time caused the clocks to move forward an hour, and I'm wondering if it is related to the scheduled scripts not executing.
My theory is that, since one of my gateway scheduled scripts is set to execute on the 23rd hour of every day, there is something behind the scenes that is adding an hour to this value after daylight savings time.
The reason I think that could be an issue, is that in the designer, my scheduled script settings are the following:
If I were to add 1 hour to it, I will get an invalid syntax error in the preview:
My theory is that something behind the scenes could be adding 1 hour this time to account for daylight savings time, causing an invalid expression error, which then causes all of the gateway scheduled scripts to not execute.
I could be totally wrong about this, but I can't think of what else might be causing these scripts to not execute. Nothing has been changed with this project for months, and suddenly the gateway schedueld scripts stop executing the same day the clocks change due to daylight savings time.
Is this just a coincidence? Or could Daylight Savings Time cause this sort of thing to happen?
