Could it be that you have systemd-timesyncd running?

BTW, this is what I do to manually/explicitly set the system time (taken 
verbatim from my vimwiki, so don't mind the wording):

Changing the Current Date:

# timedatectl set-time <YYYY-MM-DD>

Or both at once:

# timedatectl set-time <YYYY-MM-DD> <HH:MM:SS>

This commands will fail if an NTP service is enabled. The NTP service 
can be enabled and disabled using a command as follows:

# timedatectl set-ntp <true|false>

Changes to the status of chrony or ntpd will not be immediately noticed 
by timedatectl. If changes to the configuration or status of these tools 
are made, enter the following command:

# systemctl restart systemd-timedated.service

By default, the system is configured to use UTC. To configure your 
system to maintain the clock in the local time, run the timedatectl 
command with the set-local-rtc option as root:

# timedatectl set-local-rtc <boolean>
