No Date Advance – When processing a data file from a mixed array
datalogger, if the time stamp uses midnight as 2400 with “today’s” date,
the date function will convert that time stamp to 0000 hours with
“tomorrow’s” date. (This is because the algorithm used by the date
function is based on Windows’ time format, and it does not support a
2400 time stamp.) For example:
Array ID Year Julian Day Hour/Minute Date Function Data Data
10 2002 151 2200 05/31/02 22:00 1.701 193.6
10 2002 151 2300 05/31/02 23:00 1.476 31.99
10 2002 151 2400 06/01/02 00:00 1.123 106.2
At Julian Day 151 (May 31) 2400 hours, the date function produces an
output of June 1 00:00 hours. The date can be stopped from rolling
forward by using the No Date Advance check box. The output will then
be similar to:
Array ID Year Julian Day Hour/Minute Date Function Data Data
10 2002 151 2200 05/31/02 22:00 1.701 193.6
10 2002 151 2300 05/31/02 23:00 1.476 31.99
10 2002 151 2400 05/31/02 00:00 1.123 106.2
Caution should be used when applying the date function and enabling or
disabling No Date Advance, since it is possible to produce an incorrect
date. For instance, using the above example if you were to enter the
following into your select line:
3,edate(“hh:mm”;4;3;2)
with the No Date Advance enabled, you would get the output:
151 22:00 1.701 193.6
151 23:00 1.476 31.99
151 00:00 1.123 106.2
If you were to enter:
edate(“mm/dd/yy”;4;3;2),4,6,7
with the No Date Advance disabled, you would get the output:
05/31/02 2200 1.701 193.6
05/31/02 2300 1.476 31.99
06/01/02 2400 1.123 106.2
No Dashes – When the No Dashes check box is selected, the dashed line that
typically appears under the column headings will not be displayed. This option
affects all output types (PRN, RPT, HTM, and printed page).
No Summary Heading – When processing data using time series functions
(see No Summary, above), select this option to prevent the Time Series
