Notes
-----
1) The Universal Date Stamp gives the trigger time to the nearest 100
nanosecond, except for MC data that has not been through the
packer/unpacker for which it is only rounded to 20 nanosecond. It is based
on a 53 bit register 10MHz clock which started on:-
1 Jan 1996 00:00
and runs forever (= 28.5years). Due to imperfections in our mechanical
universe the clock does not run at constant rate.
The functions:-
time difference
universal_date_compare
can be used to calculate the time shift when comparing times that are
relative to different Universal Date Stamps.
2) The Local Date Stamp gives a time to the nearest centisec in GMT (no
daylight saving correction) and is equivalent to the Universal Date Stamp.
As it is of lower resolution it should be derived from the Universal
version (using universal_date_local) and NOT the other way round. The
reason for the duplication is that this form is easier for humans (helps
when debugging etc.) and will probably used for database validity ranges.
3) The Global trigger time is based on a 43 bit 50MHz clock. It must
restart/wrap every 2.04 days and will happen within a run. It gives
relative time between events (unless phase changes between them). Global
triggers are latched to (i.e. occur on) 50MHz (20nsec) clock ticks
4) KEV_NPM records the number of PMTs that were hit, regardless of the number
of photoelectrons each received. KEV_NPH gives the integrated charge in
the event.
5) KEV_DATA_SET holds the blindness results of the data splitter for the
current event. The word is used as a bit mask with the bits defined as
follows:
Bit 0 set if the event is in a data set that has been defined to be OEPN.
Bit 1-30 set if the event is in data set 1-30.
Bit 31 set if the data set is undefined.
If no bits are set the data set has not been calculated.
