want BSD-like date -r option
In FreeBSD date there's "-r" option to convert seconds since the Epoch to current date. It would be nice to have this option in illumos date.

GNU coreutils (as used by most Linux distributions) uses -r for:
display the last modification time of FILE
$ date -r /etc/hosts
Tue Jan 6 18:21:09 PST 2015
The behavior you mention is available under Linux with the syntax:
$ date --date='@1444666647'

No opinion on adding this to illumos, just pointing out however it's done it will be incompatible with another common OS.

Mac OS X, at least in Yosemite (10.10.2), includes a FreeBSD-compatible -r flag.
