clock and echo problems

[M.R.Murphy]

This is probably just a case of RTFM, but here goes:

Compaq Deskpro 386, Xenix 2.3.2, and the system clock loses an hour or
two a day. CMOS clock is ok. This seems like it probably shouldn't happen :-)

Anybody notice that under csh,
 % echo "--"
works, but under /bin/sh,
 $ echo "--"
doesn't work?
Any good reason for such behavior from /bin/echo ?
