Offset = S 00:00:00:00
This menu item allows the user to offset the time on the selected Video or LTC Timecode channel with respect to
SPG Time.
The field “00:00:00:00” is used to add / subtract time to / from SPG Time in the selected Video or LTC Timecode
channel. The sub-fields in the field “00:00:00:00” represent hours: minutes: seconds: frames. When sub-fields are
adjusted, the corresponding fields in “Running Time” reflect the changes.
Each sub-field is edited individually. A highlight cursor is displayed showing which sub-field is active and hence
editable in the field.
These sub-fields always display any offset that has been entered by the user.
If the offset time is zero or positive, a plus sign is displayed (as above); if the offset time is negative, a minus sign is
displayed.
Offset = UTC + 00:00:00:00
This menu item allows the user to offset SPG Time with respect to UTC Time.
This is where the user should enter their current time-zone offset from UTC. This offset should not include any
daylight saving offset that may be in force - Daylight Saving adjustments are handled separately (see below).
The field “00:00:00:00” is used to add / subtract time to / from UTC Time in the SPG Time menu. The sub-fields in
the field “00:00:00:00” represent hours: minutes: seconds: frames. When sub-fields are adjusted, the corresponding
fields in “Running Time” reflect the changes.
Only the “hours” and “minutes” sub-fields are editable. A highlight cursor is displayed showing which sub-field is
active and hence editable in the field. The “hours” sub-field is fully adjustable from -12 to +12. The “minutes”
sub-field is only adjustable in 15 minute intervals - this is because the smallest defined increment in the list of
global time-zones is 15 minutes.
These sub-fields always display any offset that has been entered by the user.
If the offset time is zero or positive, a plus sign is displayed (as above); if the offset time is negative, a minus sign is
displayed.
Running Time (UTC)
This menu item displays the current time, as received by the GPS system, on the GPS Date Time (UTC) menu. This
time only displays w hen a GPS solution h as been found, and the system is locked to the received data.
The field hh:mm:ss:ff displays hours, minutes, seconds and frames in the 24-hour format. Note that frames are
always displayed as 00, because this information is not included in the GPS data stream.
Nudge
This menu item allows the user to manually adjust UTC Time (where the SPG is not synchronized to an external
time source, such as GPS or NTP, i.e. when neither option is enabled in the Option Enable menu).
The field “00:00:00:00” is used to add / subtract time in the UTC DateTime menu. The sub- fields in the field
“00:00:00:00” represent hours: minutes: seconds: frames. When sub- fields are adjusted, the corresponding fields in
“Running Time” reflect the changes.
Each sub-field (except “frames”) is edited individually. A highlight cursor is displayed showing which sub-field is
active and hence editable in the field.
UTC time counts continuously. Note that each time the seconds field is nudged, the frames field is reset to zero.
This provides an easy way to set the UTC time to be coincident with your temporary reference.
This field always displays zeros in each of the sub-fields.
When GPS or NTP are enabled, the Nudge feature is disabled, and this menu line appears as either:
