NAME

  zic - Time zone compiler

SYNOPSIS

  /usr/bin/zic [ -d directory ] [ -l localtime ] [ -v ] [ filename ... ]

munnari$ uname -a
OSF1 munnari.OZ.AU V3.2 148 alpha

It goes back a long time, and isn't surprising, as OSF1 is (mostly)
a BSDish based system (user level) (with Sys V add ons, rather than
the other way).
