=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'.
