Synopsis

Contains state machinery and caching for actual conversions

Example

Convert (with all steps explicit) a UTC to an IAT time.

 #include <casacore/measures/Measures.h>
 #include <casacore/measures/Measures/MEpoch.h>
 #include <casacore/measures/Measures/MCEpoch.h>
 cout << "TAI for UTC = MJD(50237.29): " <<
 MEpoch::Convert(MEpoch(MVEpoch(Quantity(50237.29, "d")),
 MEpoch::Ref(MEpoch::UTC)),
 MEpoch::Ref(MEpoch::TAI))() <<
 endl;
