# functions to be added to the time conversion library.
# "offtime" is like "gmtime" except that it accepts a second (long) argument
# that gives an offset to add to the time_t when converting it.
-# "timelocal" is equivalent to "mktime".
+# I.e., "offtime" is like calling "localtime_rz" with a fixed-offset zone.
+# "timelocal" is nearly equivalent to "mktime".
# "timeoff" is like "timegm" except that it accepts a second (long) argument
# that gives an offset to use when converting to a time_t.
+# I.e., "timeoff" is like calling "mktime_z" with a fixed-offset zone.
