Remove the datetime keywords ABSTIME and RELTIME, which we'd been treating as
noise words for the last twelve years, for compatibility with Berkeley-eraoutput formatting of the special INVALID values for those datatypes.Considering that the datatypes themselves have been deprecated for awhile,this is taking backwards compatibility a little far. Per gripe from JoshBerkus.
