toTimeSpec() is not guaranteed to be fast, although I put in as many
optimisations as I could into the conversion functions. Each KDateTime
instance caches both the UTC value and the last time zone the instance was
converted to, whenever any conversion is done. So recalculating the UTC
value or last time zone conversion will be very fast.
