When utilizing a Hardware Time Clock in a region that practices Daylight Savings, the clock can be configured to recognize daylight savings changes. When the DLST settings are not configured on the time clock, the HCM software will house and drive the time displayed on the clock.

Additional Notes

• If the DLST settings are configured, the values must be updated on the Time Clock each year.
• If the clock is likely to lose connectivity, it is recommended that the HCM software houses the time zone, rather than having DLST configured on the hardware time clock.  

• In some cases, it is necessary to forgo the DLST setting on the hardware and instead adjust the time zone setting from our cloud-based software. If you are utilizing this method:

  • Navigate to Settings > Time and Labor Mgmt > Time and Attendance > Settings > Time Clock Config > ZK US10C Time Clocks
  • Click on the serial number of your time clock
  • Update the time zone setting to account for the one-hour adjustment
  • Click “Save”
  • Power the clock off then back on to load the new time setting.
