How Symphonie data is time stamped in UTC based on time zone and logger clock (stand-alone or internet enabled)

Symphonie raw data is always time-stamped with raw timestamps in Universal Time (UTC). Loggers do time-stamp math to calculate UTC based on the time zone you specify and the Logger clock time.

The only difference between a stand alone and a Symphonie equipped with an iPack is that the stand alone unit clock will not automatically adjust itself periodically (no time server is accessed)...clock drift could be up to two minutes per month but is typically around one minute per month.

The data is still always stored the same way...local time programmed into the logger is adjusted by the timezone programmed in the logger in order to store the data in UTC. The timestamps in the raw file have been calculated from the clock AND the timezone setting programmed in the logger.
