What is your V class synced to to get its time from ? itself ?

There are plenty of NTP servers on the internet which you can use to sync to, unless you have an atomic clock of your own somewhere you can sync to instead. Or if you dont wasnt to be dependant on an external source for your clock pick a server at your location which doesnt lose time and set this up as your NTP server for everyone else to sync to.

If it's consistent in losing 1 second per hour then you could implement a workaround by drifting the clock a single second per hour to compensate.

Consider an hourly cron job which calls 'date -a 1'. If you need it more accurate then the -a argument allows fractions of a second and you could run it more often. see man date for more information.
