OK, I believe it might be a permissions issue, but I don't understand 
why when I connect from some hosts to I get the error and 
from others I don't.

I don't see the time being wierd. I just see it generating an error 
message after reading the timezone file. I did an strace -s 512 -f -p... 
on sshd to check what it was complaining about.

[pid 16309] open("/usr/share/zoneinfo/America/Vancouver", O_RDONLY) = 7
[pid 16309] fstat(7, {st_mode=S_IFREG|0644, st_size=1037, ...}) = 0
[pid 16309] fstat(7, {st_mode=S_IFREG|0644, st_size=1037, ...}) = 0
[pid 16309] mmap(NULL, 4096, PROT_READ|PROT_WRITE, 
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2a9557c000
[pid 16309] read(7, "TZif\0\0\0\ [SNIP] ...25IT \02697\20\27)6 
\30\"S"..., 4096) = 1037
[pid 16309] close(7)                    = 0
[pid 16309] munmap(0x2a9557c000, 4096)  = 0
[pid 16309] sendto(6, "<86>Sep  6 13:50:01 sshd[16309]: Postponed 
publickey for root from ::ffff: port 38488 ssh2", 102, 

If it couldn't read the file, then that'd be a different error.

I don't think I can go any further than I have. I'm just going to have 
to ignore those messages for now.
