Set start, stop, gap, integration times

Synopsis
settimes(integrationtime, gaptime, usehourangle, starttime, stoptime, referencetime)

Description
Set various times for the simulation, including start, stop, integration, and gap times. The start and stop times are referenced to referencetime. Use either starttime/stoptime or startha/stopha. If the hour angles are specified, then the start and stop times are calculated such that the start time is later than the reference time, but less than one day later. The hour angles refer to the first source observed.

Arguments

integrationtime		Integration time
		Allowed:	Quantity
		Default:	'10s'
gaptime		Gap time between observations
		Allowed:	Quantity
		Default:	'20s'
usehourangle		Use starttime/stoptime as hour angles - else they are referenced to referencetime
		Allowed:	Bool
		Default:	T
starttime		Start time referenced to referenceepoch
		Allowed:	Quantity
		Default:	'0s'
stoptime		Stop time referenced to referenceepoch
		Allowed:	Quantity
		Default:	'3600s'
referencetime		Reference time for starttime and stoptime
		Allowed:	Epoch
		Default:	'50000d'

Example

  reftime := dm.epoch('utc', 'today');
  mysim.settimes( integrationtime='10s', gaptime='0s', usehourangle=T,
                starttime='0s', stoptime='3600s', 
                referencetime=reftime);

Here we use the Measures tool to define today's epoch which we use in settimes. Here we set a 3600 s observation after the reference time with 10 s of integration and no gap between integrations.
