Section 5. Split
Time Offset
This field specifies a time offset, in seconds, that should be applied to each
item on the Select line that uses the Date or Edate function to output a date.
The offset can be positive or negative. Each input file can have its own offset
(or no offset) for its Select line.
For example, with an input timestamp of “2008-10-09 10:25” and an offset of
3600, the timestamp output by Date(“yyyy-mm-dd hh:nn”;1;1;1;1) would be
“2008-10-09 11:25”.
This may be useful when adjusting for different time zones.
The offset will not be applied to Date and Edate functions with
only two parameters. (The two-parameter mode is backwards
compatible with the original Date and Edate functions used in
older versions of Split.) NOTE
5.3.1.3 Start Condition
A starting point may be specified to begin processing data. If the Start
Condition field is left blank, Split will start processing data at the beginning of
the data file. The starting point can be any element within the array or a
combination of elements within an array.
The font for Start Condition, Stop Condition, Copy, and Select
can be changed from the Options Menu. NOTE
The syntax can be expressed as:
e
i
[val
i
]
where e
i
= the position number of the element within the array
val
i
= the value of that element.
For example, the data in TABLE 5-1 contains seven elements per Output
Array, representing hourly data. Assume that this data file contains one month
of hourly data. To start processing data at 1500 hours on the first day, the Start
Condition is expressed as 3[1500], where 3 means the third element within the
array and 1500 is the value of that third element.
The element must match this start value exactly to trigger the start condition.
However, when starting based on time, you can enable the “Start-Stop
On/After Time” function to trigger the start of processing when the exact time
is found or at the first instance of data after that time has occurred. This option
is found on the Output tab, Other button.
