Guru Time is set to UTC and does not honor daylight savings time changes, so it may be off by 1 hour while the local time correctly implements Daylight Savings time. The local time relies on accurate and up to date information about the current Daylight Savings time in your location stored in the Operating System. For ArcaOS, this is a string that can be manually updated to match any recent changes. For Linux NUC, apply relevant TZ package to get up to date information.
