Notes from the Maintainers

Source: europe (Lines 3389 to 3404)

From Tim Parenti (2014-07-03):
Asia/Khandyga covers parts of (14, RU-SA) Sakha (Yakutia) Republic:
14-28	****	Tomponsky District
14-30	****	Ust-Maysky District

From Arthur David Olson (2022-03-21):
Tomponsky and Ust-Maysky switched from Vladivostok time to Yakutsk time
in 2011.

From Paul Eggert (2012-11-25):
Shanks and Pottenger (2003) has Khandyga on Yakutsk time.
Make a wild guess that it switched to Vladivostok time in 2004.
This transition is no doubt wrong, but we have no better info.
