Truetime Format
The format of the Truetime string is identical to the Sysplex format. The only difference between
the two is that the Sysplex format always uses UTC time. The time contained in the Truetime format
depends on the time mode of the Tempus LX. (See Time Mode in Chapter 5 - Front-Panel Key-
pad and Display
and
gsystimemodeconfig
in
Chapter 6 - Control and Status Commands
.) For
example, if you want an output with this string format that uses Local Time, then select the Truetime
format.
EndRun Format
The time contained in this string depends on the time mode of the Tempus LX. For example, if you
want the time in this string to be UTC, then set the time mode of the Tempus LX to UTC. (See
Time Mode in
Chapter 5 - Front-Panel Keypad and Display
and
gsystimemodeconfig
in
Chap-
ter 6 - Control and Status Commands .) The following string is sent once each second:
T YYYY DDD HH:MM:SS zZZ m<CR><LF>
T is the Time Figure of Merit (TFOM) character described in
Appendix E - TFOM.
This is the “on-time” character.
YYYY is the year
DDD is the day-of-year
: is the colon character (0x3A)
HH is the hour of the day
MM is the minute of the hour
SS is the second of the minute
z is the sign of the offset to UTC, + implies time is ahead of UTC.
ZZ is the magnitude of the offset to UTC in units of half-hours.
Non-zero only when the Timemode is Local (see Chapter 5).
m is the Timemode character and is one of:
G = GPS
L = Local
U = UTC
<CR> is the ASCII carriage return character (0x0D).
<LF> is the ASCII line feed character (0x0A)
