How does the logger and ZENTRA Cloud handle Time Change
The loggers are keeping track of UTC time.
This time is updated via the GPS receiver daily or from the ZENTRA Cloud server on each data upload. ZENTRA Cloud uses a time zone offset to display with measurement data in the "local time" of the logger.
ZENTA Cloud defaults to the time zone offset setting stored in the logger to calculate the local time.
The logger's time zone setting comes from two settings: ZENTRA Utility software and the cellular network. During the transition to or from Daylight Savings Time, the device may get updated time zone information from the cellular network. Sometimes this transition doesn't happen immediately. Sometimes the cellular network the device is using doesn't transmit time zone information.
You can use the time zone override feature of ZENTRA Cloud to enforce a specific time zone for your measurement data.
