AM (6 july 2004) The above link is stale. Any updates available?
KBK (7 July 2004) The functionality proposed for the clock command in TIP #173 includes a %J format group that gives the Julian Day Number. Since TIP #173 also proposes using the -format option on [clock scan], you can do input as well of output of Julian Day.
