Subject: [musl] [PATCH v3 1/2] Remove unnecessary if in __secs_to_tm
Date: Sun, 28 Feb 2021 20:27:11 +0100	[thread overview]
Message-ID: <20210228192712.1666688-1-maandree@kth.se> (raw)
In-Reply-To: <20210228150912.1532943-1-maandree@kth.se>

Since years divisible by 100 but not by 400 are not leap years,
q_cycles can at most be 24 (DAYS_PER_100Y / DAYS_PER_4Y == 24).
