    Server time ticking clock v2.0 Updated by js-x.com

    -------

    Updated & rewritten for internal use by RL.SE in April/May 2009:

    o   Clock unnecessarily waited 1s before first display of time. Fixed,

    o   Removed unused functions MakeArrayday() & MakeArraymonth()

    o   Unused variable runTime removed

    o   Uses universal 24 hour format instead of ancient AM/PM

    o   Code beautified / indented / made more readable

    o   Added rl_adjust() for setting/adjusting the time from
        outside of JavaScript. The calling routine in e.g. PHP
        should await the beginning of the second before calling
        rl_adjust()

    o   Added showPCtime() to also show client's own time

    o   Tested FF3.1 and FF3.5 (and IE8, if someone still uses IE...)

    o   Added larger clock as a popup for those with low vision
