Subject: DST change issue for timezones in southern hemisphere
Date: Mon, 6 Mar 2017 12:44:53 +0200	[thread overview]
Message-ID: <34ea8f18-42d9-7817-7595-00435ac24b22@direct.lv> (raw)

Hi!

For some reason DST change in southern hemisphere occurs 1 hour late 
when clock is turned backward and 1 hour early when clock is turned forward.

For example, timezone for spec for Brazil is:
BRT3BRST,M10.3.0/0,M2.3.0/0
Which means that DST change occurs at midnight.

Output of date for both DST changes:

~# date
Sun Feb 19 00:59:59 BRST 2017
~# date
Sun Feb 19 00:00:00 BRT 2017

~# date
Sat Oct 14 22:59:59 BRT 2017
~# date
Sun Oct 15 00:00:00 BRST 2017

I've tested the same code on same hardware but with uClibc library 
instead of musl and it works fine.
