In this FW release ATS25AMP does not save time offset in memory.
RTC time from NTP server is 14:12, if i change in setup clock setting to 15:12 (summer time) it works until reboot.
When switched off and then switch on it returns to 14:12

Thanks @Binns

I use ATS25 AMP, after updating to 4.2 HiZ/50ohm switch does not work. At least no led switching.
