Changing the Local Time of a Digital Tachograph

UTC vs Local Time explained:  Your tachograph records in UTC (Universal Time) which works independently of daylight-saving clock changes or time zones.  UTC is equivalent to Greenwich Mean Time (GMT).  Changing the clock on your tachograph display (Local Time) is technically cosmetic, but of course without changing this time, the ‘on screen’ messages could be confusing for the driver. It is worth noting that all data and printouts from the tachograph will be generated in UTC time, even if the display is set to show Local Time.

Drivers need to remember that UTC is one hour behind British Summer Time (BST). So, between 01.00 on the last Sunday in March and 01.00 on the last Sunday in October drivers must account for the difference when manually inputting activity details in the digital or smart tachograph.

When to change the Local Time: the local time will fall back one hour at 01:00 on the last Sunday in October and roll forward one hour at 01:00 on the last Sunday in March
