ANYTIM2INTS takes any of the three representations and returns a
structure with the internal representation. The structure has a
.TIME and a .DAY field. An example is:
IDL> a = anytimts('23-jun-92 3:00')
This routine has an optional keyword input to allow the user to offset
the input time by some number of seconds. If the input is an array
of times, then the offset can be a scalar value or it can be an array
of offsets which is the same length as the input. For example,
IDL> a = anytimts(roadmap, off=60.5)
IDL> a = anytimts(roadmap, off=off)
The following command will set up a structure which has
has the dates of 100 Mondays starting on 7-Jan-91 (since 7-Jan-91 is
a Monday and there are 86400 seconds in a day). The second example
sets up a 500 element array with times separated by 90 seconds.
IDL> dates = anytimts('7-jan-91', off=findgen(100)*86400.*7)
IDL> tt = anytimts(!stime, off=findgen(500)*90.)
