DATTIM is the date and time to be used by GEMPAK programs.
DATTIM is an 11-character string entered as YYMMDD/HHMM, where:
YY is the last two digits of the year
MM is the month
DD is the day of the month
/ is the date and time separator
HH is the hour
MM is the minutes past the hour
The part before the / is the DATE; the part after the / is the TIME.
DATTIM may be abbreviated. If the input has no / , it is assumed
to be the TIME part. An abbreviated version of either TIME or DATE
is assumed to be the part closest to the /. The rest of the
standard time is obtained from the last time in the file. For example,
if the last time in the file is 940515/1200 the following translations
will be done:
13/11 ----> 940513/1100
13 ----> 940515/1300
13/ ----> 940513/1200
0412/1300 ----> 940412/1300
A list of times may be entered for DATTIM. Times in the list must be
separated with semicolons. For example:
In the above example, the times are:
DATTIM may also be entered as a range. The first and last times must
be separated by a minus sign. For example:
A range with an increment may also be entered using minus signs as
separators. The format of the increment is hhhmm. If the increment
is one or two digits, it is assumed to be in hours.
The following options are also valid for DATTIM:
LAST -- the last time in the file
LIST -- lists all times and waits for input
ALL -- all the times in the file
/ALL -- all the times for a single DATE.
If /ALL is entered, all the times for the most recent date are processed.
If /ALL is appended to a specific date, then all the times for that
date will be processed.
