SCANTIME returns the timerange covered by a scan defined by an index table.
It may be used to set the TIMERANG adverb for a single scan given a scan
number as shown by LISTR with OPTYPE = 'SCAN' as in the following example.
TIMERANG = SCANTIME(5)
To have SCANTIME print the scan time range to the terminal type, for the
3rd scan as an example:
The starting time of the scan is rounded up to the nearest second and the
ending time of the scan is rounded down to the nearest second so that time
returned time range is wholly contained within the scan.
If the argument specifies a scan that is not in the index table then the
returned value is all zeros.
