I’m not quite sure if you have the opportunity to solve the problem (its not really an error in my eyes) is yet but one way that I found of overcoming the situation is to make sure that the server (which in my case is located in a data centre offshore) is the same time zone as the client machines accessing the server.
I would be very reluctant to try and update every single time zone and time on each of the client machines as this will take a lot of time and be quite painful for the end-user.
On a Debian based (such as Ubuntu) Linux server you can change the time zone relatively easily.
Step one find out what time zone is available to you by typing the following command.
root@server:# timedatectl list-timezones
(scroll down using the arrow keys to find the appropriate time zone)
root@server:# timedatectl set-timezone Africa/Johannesburg
If all of your client systems are within the same time zone that Johannesburg is in you should no longer get the error message.
I hope this helps
