Possible problems with time triggers and daylight saving time transition

[Triple-S]

Hello,
I have a script which is supposed to run every 5 seconds which I achieve with the time trigger @time_trigger("period(now, 5s)").
Today night was the transition from stupid daylight saving time to regular time so the hour from 2 to 3 am was repeated. Today morning I noticed that between the second 2 am and the second 3 am my Script did not run. Afterwards it continued to run perfectly fine. Since my script is written such than an error message is logged whenever something fails and there were no error messages in the log I conclude that there was probably a problem with the trigger.
Could somebody who knows how it works please look into this?
Thank you and best regards
