Cut off interval output at the given year(s).
Cutoff times are computed using the proleptic Gregorian calendar with year 0
and with Universal Time (UT) ignoring leap seconds.
The lower bound is exclusive and the upper is inclusive; for example, a
.I loyear
of 1970 excludes a transition occurring at 1970-01-01 00:00:00 UTC but a
.I hiyear
of 1970 includes the transition.
Cutoffs are at the start of each year, where the lower-bound
timestamp is exclusive and the upper is inclusive; for example,
.B "\*-c 1970,2070"
selects transitions after 1970-01-01 00:00:00 UTC
and on or before 2070-01-01 00:00:00 UTC.
The default cutoff is
