Subject: [PATCH v3 3/3] tst: Add test for clock_settime
Date: Wed, 10 Feb 2021 11:37:10 +0100 [thread overview]
Message-ID: <20210210103710.1325-3-lukma@denx.de> (raw)
In-Reply-To: <20210210103710.1325-1-lukma@denx.de>
This code brings test to check if time on target machine is properly set.
To avoid any issues with altering the time:
- The time, which was set before the test was executed is restored.
- The time is altered only when cross-test-ssh.sh is executed with
--allow-time-setting flag
