BAC-19xxxx FlexStat Application Guide 25 AG200824A
APPENDIX: UTC OFFSET TIME ZONES
To select a time zone and optional DST, see Set Clock (Menu Options) on page 5.
If the FlexStat is used in a BACnet network with UTC (Coordinated Universal Time) synchronization (via broad-
casting or addressing a single thermostat) set the UTC Offset value. The UTC Offset value is in minutes and
corresponds to the distance of the local time zone to the zero degree meridian. In stand-alone operation or
networks that do not have UTC broadcasts, setting this value is NOT necessary.
UTC (also commonly known as Zulu or Greenwich Mean Time) is, for example, 5 hours ahead of Eastern Stan-
dard Time or 4 hours ahead of Eastern DST (Daylight Saving Time). See the chart below for more time zone
conversions.

*Minor parts of the named areas may be in other time zones.
**May also need to convert from 24 to 12 hour format.
***The BACnet standard for this offset value is: “The time zones to the west of the zero degree meridian shall be positive values,
and those to the east shall be negative values.” The value is in minutes, not hours.
The UTC-Offset in the FlexStat display menu has no provision for
a – sign. Use KMC software to add the – sign for time zones in the
Eastern hemisphere as shown on the right.
