Subject: [PATCH 2/5] trace-cmd library: Remove useless check before applying ts offset
Date: Wed, 28 Apr 2021 15:28:36 +0300	[thread overview]
Message-ID: <20210428122839.805296-3-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20210428122839.805296-1-tz.stoyanov@gmail.com>

Checking if offset is non-zero before adding to the timestamp is useless,
as adding 0 will not change the timestamp.
