Time Zone and DST Mode
(DST = Daylight Saving Time)
Reference Input
: The module uses UTC as an internal time base. The following settings and
the settings
Offset Reference Input
at the
Time Zone
tab are needed to convert
the data of the real
–
time reference input into UTC.
AUTO
Time, date and status data of the signal input indicate the time zone of
the real
–
time reference. The real
–time reference may utilize DST. “Offset
from UTC“ and “DST Bias“ at
Time Zone
are taken into consideration.
UTC
The time zone of the real
–time reference does not utilize DST, the ‘UTC’
status will be set for internal
use. “Offset from UTC“ at
Time Zone
is
taken into consideration!
Standard Time Only
The time zone of the real
–
time reference does not
utilize DST, the ‘Standard Time’ status will be set for internal use. “Offset
from UTC“ at
Time Zone
is taken into consideration.
Daylight Saving Time Only
The time zone of the real
–
time reference does not
switch to DST, the ‘DST’ status will be set for internal use. “Offset from
UTC“ and “DST Bias“ at
Time Zone
are taken into consideration.
Local Time Zone
: These settings determine the status of the local time zone and set
conditions for an update of the time code generator with time & date of the real
–
time reference.
Auto + Reference Check
The local time zone utilizes DST; the switching occurs
automatically according to the settings at
Time Zone
. Un update
(according to the “Periodically” setting at
Mode of Local Time Zone
Synchronization
) occurs only if the time of the reference differs less than
one minute from the expected time value.
UTC + Reference Check
: The local ti
me zone does not utilize DST, the ‘UTC’ status
will be set for internal use. “Offset from UTC“ at
Time Zone
is taken into
consideration! Un update
(according to the “Periodically” setting at
Mode of Local Time Zone Synchronization
) occurs only if the time of
the reference differs less than one minute from the expected time value.
UTC
The local time zone does not utilize DST, the ‘UTC’ status will be set for
internal use. “Offset from UTC“ at
Time Zone
is taken into
consideration!
Standard Time Only
The loca
l time zone does not utilize DST, the ‘Standard
Time’ status will be set for internal use. “Offset from UTC“ at
Time Zone
is taken into consideration.
Daylight Saving Time Only
The local time zone does not switch to DST, the ‘DST’
status will be set for in
ternal use. “Offset from UTC“ and “DST Bias“ at
Time Zone
is taken into consideration.
Same As Reference Input
The local time zone follows the status of the real
–
time
reference input (UTC, Standard Time, DST). A DST switching of the local
time zone occurs only if the time zone of the real
–
time reference
switches. “Offset from UTC“ and “DST Bias“ at
Time Zone
are taken
into consideration.
