Fixed dcl timestamp issue in dosta_abcdjm_dcl, flort_dj_dcl, and spkir_abj_dcl. 
Note: only setting the internal timestamp in the __init__ method of the 
xxxParticle class has been changed.

The bug was that the fractional seconds precision was being ignored.

There is a new utilities.py file that can contain methods that can be used 
by more than one parser. Methods can be added to this.
