+.SH LEAP SECOND LIST FILE
+If the environment variable LIBMSEED_LEAPSECOND_FILE is set it is
+expected to indicate a file containing a list of leap seconds as
+published by NIST and IETF, usually available here:
+http://www.ietf.org/timezones/data/leap-seconds.list
+
+If present, the leap seconds listed in this file will be used to
+adjust the time coverage for records that contain a leap second.
+Also, leap second indicators in the miniSEED headers will be ignored.
