Resolution
The Time Zone\DST settings are in Registry under (may be different depending on the operating system):

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones

For modifying the Keys, Windows Time Zone Editor can be used. This tool can be downloaded from https://www.southsoftware.com/tzedit.zip

Additional Notes:

- The DST start/end date in the meter should be the same as in the operating system.
- If for any reason the DST start/end dates in the operating system are changed, in ION Setup the DST start/end dates can be updated to have the same settings. This can be done with selecting Update all available daylight saving dates check box when editing Clock | Timezone:
