Thanks for your reply, David. I didn't realize that adjtimex() is
Linux-specific(). Anyway, I've tried the -a option of rdate now but
unfortunately it also fails:
sh-4.0# date
Thu Sep 24 02:16:02 GMT 1903
sh-4.0# rdate -o 123 -nvv -a 0.debian.pool.ntp.org
.
rdate: Could not adjust time of day: Invalid argument
strace shows:
gettimeofday({2203577094, 599408}, NULL) = 0
gettimeofday({2203577094, 600709}, NULL) = 0
write(2, "rdate: "..., 7rdate: ) = 7
write(2, "Could not adjust time of day"..., 28Could not adjust time of day) = 28
write(2, ": "..., 2: ) = 2
write(2, "Invalid argument\n"..., 17Invalid argument
) = 17
The full log from strace is attached.
Do you know if this problem can be addressed in a platform-neutral way?
