=head1 MODE
Check time offset of server with ntp server. Use local time if ntp-host option is not set.
SNMP gives a date with second precision (no milliseconds). Time precision is not very accurate.
Use threshold with (+-) 2 seconds offset (minimum).
=over 8
=item B<--warning-offset>
Time offset warning threshold (in seconds).
=item B<--critical-offset>
Time offset critical Threshold (in seconds).
=item B<--ntp-hostname>
Set the ntp hostname (if not set, localtime is used).
=item B<--ntp-port>
Set the ntp port (Default: 123).
=item B<--timezone>
Set the timezone of distant server. For Windows, you need to set it.
Can use format: 'Europe/London' or '+0100'.
