DST (daylight saving time) not switching back?

[rrednaxela]

After falling back from DST to normal time on Sunday morning the time on my BHT-002-GALW didn't adjust. Today around 20:00 I clicked save on the 'Configure clock' page, and after the reboot the time was ok.
I have configured the defaults, pool.ntp.org and time zone server http://worldtimeapi.org/api/ip
How often does the software update the time?
I have 2 thermostats on 1.18, same behavior on both.

Klaus pulled that part of my fork and there was a bug in my Time Zone Implementation (mixed Northern and Southern Hemisphere).

Check fashberg/WThermostatBeca#62 and
fashberg/WThermostatBeca@274a38e

Nope. Completely different here and no Northern/Southern Mismatch https://github.com/klausahrenberg/WThermostatBeca/blob/master/WThermostat/src/WClock.h#L515
Then something different.

@rrednaxela You shoud share a screenshot of your TimeZone Settings

just the defaults

Provided that the time was correct after reboot, it seems the condition in line 129 is not met? Or it never gets there?
I looked a bit at

WThermostatBeca/WThermostat/src/WClock.h

Line 105 in 4e76dfc

validTime->setBoolean((lastNtpSync > 0) && ((!this->useTimeZoneServer->getBoolean()) || (lastTimeZoneSync > 0)) && (now - lastTry < (3 * 60 * 60000)));

• lines 112, 129:
  How much is 60000? 1 minute (according to comment in L104)?

What is then the point of " (now - lastTimeZoneSync > 60000)" in L129? Only update timezone if last timezonesync was more than 1 min ago? If the whole loop anyway runs only every 3 hours?

Bit of an old topic, but found out the same, but the other way around. DST settings were not applied after the 27th of March. I changed the NTP server to nl.pool.ntp.org, and after a reboot the time was correct again.

Same here today with version 1.36.
Clock didn't change with this settings:
