MK4 Clock Incorrect After NZ Daylight Saving Change

PrusaLink version: N/A (bundled with firmware)

Printer type: Prusa MK4S

Description of the bug: The printer clock does not correctly adjust for New Zealand daylight saving time. After the spring clock change, the printer’s time is one hour behind the correct local time.

Steps to reproduce:

Set the printer to local time in New Zealand.

Wait for the daylight saving time transition in spring.

Observe that the printer time is one hour behind the correct local time.

Expected behavior: The printer should automatically adjust for daylight saving time in New Zealand.

Actual behavior: The printer does not adjust correctly, causing the time to be off by one hour.
