--- Comment #3 from Howard Chu hyc@openldap.org --- This ticket looks invalid to me. In particular, on MacOSX the manpage states:
date [-jnRu] [-r seconds | filename] [-v [+|-]val[ymwdHMS]] ... [+output_fmt]
-r seconds Print the date and time represented by seconds, where seconds is the number of seconds since the Epoch (00:00:00 UTC, January 1, 1970; see time(3)), and can be specified in decimal, octal, or hex.
-r filename Print the date and time of the last modification of filename.
And using "-r seconds" works fine on my Mac.
