Commentary

Time values come in several formats.  The oldest format is a cons
cell of the form (HIGH . LOW).  This format is obsolete, but still
supported.  The other formats are the lists (HIGH LOW), (HIGH LOW
USEC), and (HIGH LOW USEC PSEC).  These formats specify the time
value equal to HIGH * 2^16 + LOW + USEC * 10^-6 + PSEC * 10^-12
seconds, where missing components are treated as zero.  HIGH can be
negative, either because the value is a time difference, or because
it represents a time stamp before the epoch.  Typically, there are
more time values than the underlying system time type supports,
but the reverse can also be true.
