Zonar Helps You With Daylight Savings Time

This will generate common questions on how Daylight Savings Time is handled in ZLogs, the driver's record of duty status.

Unfortunately there are no official regulations or interpretations addressing documenting Daylight Savings Time on the driver's record of duty status; other than an informational email, so it is really open to interpretation.

When you “lose” an hour in the spring (spring forward), your Zlogs grid view will display “-1” from 2:00 a.m. – 3:00 a.m., with no activity. The driver could also comment in the notes area “DST” or “daylight savings” when updating their next duty status. At the end of your day, the total will be 23 hours, taking into account the lost hour.

If you are taking a required off-duty break at the time, make sure it's long enough without counting the lost hour.

Handling the 34-hour restart

The fact that the clock springs ahead has no effect on the 11-hour driving limit, the 14-hour window (which is based on consecutive time), or the 10-hour off-duty requirement (also based on consecutive time). Zlogs will calculate if for your after the 3:00 a.m. time period.

Similarly, for a restart, the driver will still need to be off for 34 consecutive hours. For example, if the driver is off from 9 p.m. on the 7th until 7 a.m. on the 9th, the off duty clock will display 33 hours due to the time change. Therefore, the driver will need to start the break by 8 p.m. or stay off duty until 8 a.m. to satisfy the rule. In either case, the break must be 34 actual hours long even if the clock jumps ahead. No freebie hour!!
