Radio clock: (depending on DCF77 or GPS)
DCF77 receiver: The radio clock currently runs on XTAL
GPS receiver: has not yet verified its possition
Time: Daylight saving in effect.
Unless the UTC status bit is set, the time contained in the data structure represents local daylight saving time.
Radio clock: Has synchronized after last reset.
The radio clock has synchronized at least once after the last reset.
Most of the Meinberg time adjustment programs wait until this bit is set
before they start adjusting the computer's system time. However, those
programs can also be configured to ignore this status bit and do the
adjustment immediately.
Time: Announcement of start or end of daylight saving time.
This bit is set during the last hour before local time switches from
or to daylight saving. This bit may not be included in IPX packets
since this information can not be derived from the computer's
operating systems.
Time: UTC.
This bit is always set if the time read from the radio clock is UTC
rather than local time. UTC never switches to daylight saving time.
Time: Announcement of leap second.
The time when a leap second must be introduced is determined by the
International Earth Rotation Service (IERS). That information
is usually broadcasted by time transmitters.
Analoguous to the DCF77 Coding Scheme
this bit is set during the last hour before the leap second is
inserted.
Radio clock: Time has been modified via interface.
The radio clock's time has not been set from DCF77 or the GPS satellites but has been
modified via the clock's interface.
Radio clock: Time is invalid.
The time read from the radio clock's real time clock after power-up is
invalid. This may happen if e.g. the radio clock's backup battery is
discharged.
In the IPX broadcast packets this bit may also be set if the radio clock
connected to the transmitting computer fails.
