Section 3. Report: SPLIT
PC208W, Version 3.3, Instruction Manual 3-13
2[-3]:3[-120,60] tells SPLIT to find the closest 60 minute interval that is less
than the PC time minus 3 days and 2 hours. If the PC time is the day of year
159, hour 0017, SPLIT will start reading on data output at 2200 hours on day
155.
2[-3]:3[-120]:4[20,5] tells SPLIT to find the closest 5 second interval that is
less than the PC time minus 3 days, 2 hours and 20 seconds. If the PC time is
27 seconds after noon on day 30, SPLIT will begin reading on data output at
1000 hours and 05 seconds on day 27.
SPLIT will not start reading if the exact specified starting
time cannot be found. The interval (5 minutes, 60 minutes,
and 5 seconds in the examples above) must be evenly
divisible into 60 minutes.
•
If the start time is a certain number of days prior to the PC
time, the file will be processed beginning at midnight of the
day specified.
•
To specify a start time in minutes from the current PC time,
you must also specify a day parameter of [-0]. Otherwise,
processing will begin at the first instance in the data file that
the minutes parameter equals the current minutes.
•
If you are specifying a start time in minutes from the current
PC time, the time you specify cannot be a value that would
push the start time past midnight (e.g., at 9 a.m., specifying
a start condition of 2[-0]:3[-600], which would be a start
time of hour/minutes equals 2300). If you do, the start
condition is never found and the file is not processed.
3.3.2.3 Using Time Synchronization While Starting Relative to PC Time
Split tries to time-sync files to the top of the hour when starting relative to PC
time. If you are synchronizing files where the data output interval is not at the
top of the hour, you will need to specify an interval in the Copy Condition that
represents a window of time in which Split should look for the hour/minute.
For instance, if your data is output 50 minutes into a 60 minute interval (and
therefore, your time stamps are 50, 150, 250, 350...2350) your Start Condition
and Copy Conditions for the first file might look like the following:
Start Condition
2[-1]:3[50]:
Copy Condition
1[106]and3[60,10]
Where:
element 1 is the array ID
element 2 is the Julian day
element 3 is the hour/minute
