Hello forum,
I have data coming from GPS Track points where, for example,
the first and last track point entries in a 33km snowshoeing trek in
April are of the form
({.,{:) tp_in_lap_x >45{laps
+--------------------+--------------------------------+
|2007-04-21T10:15:08Z|44.1936 _73.9555 646.624 5.10308|
+--------------------+--------------------------------+
|2007-04-22T00:06:59Z|44.1934 _73.9554 634.607 33385.9|
+--------------------+--------------------------------+
I would like to use the time info numerically and can
do what I need by ripping the time/date string apart
and creating time in seconds; but when the date changes
during the trek come into play, as above, the details
become complex (leap days, etc).
Are there standard J utilities for converting Date/time
text into a standard numeric form that accounts for
the complexities of dates?
Best,
Cliff
