You need to adjust a PIPE or Downloader clock due to beginning or ending Daylight Saving Time (DST).




The clock in the PIPE, Mobile Downloader or Modem Downloader is synchronized to the Guard1 Plus PC’s clock at the end of each download. It is important to synchronize the device clock as soon as possible after a time change to ensure your patrol data is timestamped correctly.


To adjust your devices for Daylight Saving Time changes:


  1. Just before the time change takes effect (or as soon as practical after the change), download all PIPEs, Mobile Downloaders and/or Modem Downloaders.
  2. Wait until the DST change takes effect on the PC. (Most PCs are set to automatically adjust when DST changes; however, you may have to adjust the PC clock manually.)
  3. After the change takes effect on the PC, adjust the device clocks as follows:


More Information

Downloading your devices before the DST change takes effect and synchronizing them after the change takes effect ensures that all of your patrol data has the correct timestamps.


If you do not synchronize your devices immediately after the time change, the patrol data collected between the time the DST change takes effect and the next download will be -1 hour in the Spring and +1 hour in the Fall.


IP Downloader does not require any intervention - its onboard operating system will handle DST changes.
