_NAME_
get_time_stamps_of_days_structs

_PROTOTYPE_
stamps = get_time_stamps_of_days_structs(day1996, structToUse)

_SHORT-DESCRIPTION_
Get a list of the time stamps of a particular data type for a given day

_DESCRIPTION_
Get a list of the time stamps of a particular data type for a given
day.  The time stamps returned are those starting at the data valid
at second zero of the day and ending just before the data which is
valid at second zero of the next day.  Any intervals of missing data
for the day return values of -1 for their time stamps.  Beware that
both start and stop time stamps are returned.  For periodic data types,
this means all of the stop time stamps will be set to -1 (because
they have no stop time stamps.)

_SHORT-CODE-SAMPLE_
day1996 = 703
structToUse = {L1CrisCommandEcho}
stamps = get_time_stamps_of_days_structs(day1996, structToUse)
i = 0
while (stamps[i] NE 0) do begin
    print, i, stamps[i], stamps[i+1]
    i = i + 2
endwhile

_INPUT_
* day1996 is the day-of-1996 of interest.
* structToUse is an instance of the data structs of the data type of interest.

_OUTPUT_
* An array of start and stop time stamps, terminated by a zero value.
The array is arranged such that startStamp[0] is followed by stopStamp[0],
followed by startStamp[1], and so forth.
