Description
So far, the following code produces an observation with a reference time at the GammaLib time reference:
>>> import gammalib >>> import ctools >>> from cscripts import obsutils >>> obs = obsutils.set_obs(gammalib.GSkyDir(),0.0,1800.0,1.0,1.0,100.0,5.0,'South_50h','prod2','') >>> print(obs.gti()) === GGti === Number of intervals .......: 1 Ontime ....................: 1800 sec Elapsed time ..............: 1800 sec MJD range .................: 55197.0007660185 - 55197.0215993519 s (TT) UTC range .................: 2010-01-01T00:00:00 - 2010-01-01T00:30:00 s (TT) Reference MJD .............: 55197.0007660185
Instead, the CTA reference time should be used.
Recurrence
No recurrence.

The GTI time reference is now set to the CTA time reference in GCTAEventList, GCTAEventCube and GCTACubeExposure.
Furthermore, the CTA time reference has been introduced as a constant in ctools, accessible via ctools::time_reference in C++ and ctools.time_reference under Python. The ctools::time_reference() method has been removed, the time reference is no longer a property of a ctool.
The time reference is now used in obsutils to set an observation with the CTA time reference. The above code gives now:
>>> print(obs.gti()) === GGti === Number of intervals .......: 1 Ontime ....................: 1800 sec Elapsed time ..............: 1800 sec MJD range .................: 51544.5 - 51544.5208333333 s (TT) UTC range .................: 2000-01-01T11:58:56 - 2000-01-01T12:28:56 s (TT) Reference MJD .............: 51544.5
