Timestamps And Time Zones On Your D400 - GE Multilin D400 Instruction Manual

Timestamps and time zones on your D400

124
All timestamps on the D400 are stored in UTC (coordinated universal time). Table 28
explains how time zones are handled by various components of the D400 and how this
behavior can be configured.

The IEC 60870-5-103 Client and IEC 60870-5-101+104 client applications are not available
in this release.
The IEC 60870-5-101+104 application uses a slightly different concept for local to UTC time
conversion in order to be consistent with the D2x product family. If the master is in a
different time zone, you should set the Time Mode field to Set local/use local time. When
the master time synchronizes the application, the application calculates the difference
between the internal D400 UTC clock and the master's time. The application then applies
this difference to the UTC timestamps it reports to the master. In effect, it automatically
calculates the time offset.
GE INFORMATION
CHAPTER 10: INTRODUCING THE D400 CONFIGURATION
Time zone handling
For all of the time zone features
described in this document to
D400
work properly, the
hardware clock must be set to
UTC using the appropriate
D400
BIOS setting.
Can be set to local time or UTC,
as desired.
The timestamp is converted to
UTC from the configured offset
or is left unmodified if no offset
is configured.
The timestamp is converted
from UTC to the configured
offset or is left at UTC if no offset
is configured.
All time-stamped data is shown
to you using the configured
D400
time zone setting.
All time-stamped data is shown
to you using the time zone
configured on the remote PC.

Configuration Method
Configured using the d400cfg utility. >
"Set System Clock" on page 146
Refer to the user documentation
provided with the device or master
station. If the device's clock is offset
from UTC, the same offset should be
configured in the corresponding client
map file (see below).
Defined by the Time Offset field in the
D400
client map files. Refer to
