Tim, please read fully and respond to the issues raised. You are falling
into the imprecision of language trap, too.

Now you are being imprecise. Do you mean UTC time zone setting or UTC
hardware clock setting with and without agreement between actual hardware
clock setting and the UTC/LOCAL indication in /etc/adjtime (the check box
on the time zone setting tool)?

This is known working:
     HARDWARE    CHECKBOX    TIMEZONE
        UTC         UTC         ANY
        LOCAL       LOCAL       ANY

These are known to break at least NTP:
     HARDWARE    CHECKBOX    TIMEZONE
        UTC         LOCAL       ANY
        LOCAL       UTC         ANY

Do all four work for cups? (I'd rather suspect it would unless there is
an SSL connection being set or there is a sanity check in CUPS that does
not seem to be published.)

You still ignore the correct two places that must agree for "everything"
to work, the setting for the motherboard clock must be either UTC or local
time and that information must be telegraphed to the OS with the value in
the third line of "/etc/adjtime" which is apparently set by the appropriate
checkbox on the time zone setting panel.

He has said he made it correct. Apparently he meant making the motherboard
clock and the checkbox agree. He was NOT talking about timezone setting.

At worst Aaron is guilty ONLY of imprecision in telling us what he had
to do. We cleared this up in private emails.
