To disable:
time daylight-time-rule none
The switch internally works in UTC, so just the representation is changed not the clock itself.
If you want to set the time for Poland, in addition to the daylight-time-rule, you should set the time offset:
time daylight-time-rule western-europe
time timezone 60
If you then configure NTP, all should be set:
timesync ntp
ntp unicast
ntp server 192.168.1.1
ntp server 192.168.4.1
ntp enable
Replace the IP addresses with your NTP IP addresses.
