@Scheduled method not triggered on start of daylight savings time

[ropoman]

I am in CEST timezone. The server was running fine for several days until on March 31st the two following scheduled methods were not called:

@scheduled(cron = "0 30 3 * * ?")
@scheduled(cron = "0 0 19 * * ?")
These were NOT CALLED on March 31st, but on April 1st everything was working again

@scheduled(cron = "0 0 * * * ?")
This was called every hour

You are on a very old version of Spring Boot, one which uses Spring 5.3.3, Spring Boot 2.4.x has been out-of-support for quite some time. Try the newest version to see if the issue has been resolved. DST issues have been fixed in Spring 5.3.7, 5.3.16 and 5.3.17.

As mentioned by Marten, please use a supported Boot version. Spring Framework 5.3.x still has OSS support, but you should first test against the latest maintenance version.

I'm closing this issue for now but we can reopen it if you provide a sample application that demonstrates the problem with the latest maintenance version of Spring Framework.

Thanks!
