Is there a standard definition for time that people have been using ?
Currently I have defined time as the set Year,Day,Hour,Min,Sec,Milsec
which suits my purposes. However if there is an already existing standard
I am certainly willing to change.
I have been struggling with another problem for a week or so, and I would
sure appreciate your help with it. Suppose I have an variable of rank 2
with dimension names TIME and FIELD and dimsizes UNLIMITED and 3 eg:
TIME FIELD
0 1 2 4
1 3 4 1
2 5 6 7
What is the correct (or standard way) of labelling the individual elements
of
FIELD (ie the three columns) ? Currently I have abandoned using a single
variable since I couldn't figure out a "standard" way of doing it. I guess one
method would be to create new attributes and make up a naming convention, but
this would not be standard and I am trying to make my data sets as easily
transportable between different plotting/analysis packages as possible.
I am also not sure if "splitting" FIELD into 3 variables has significantly
affected the time it takes to read a single TIME and FIELD record. Any help
would be greatly appreciated.
best regards
