JavaScript
Components: Clocks Doing
several Clocks with hopefully not too much overhead
Credit: See link next to each clock.
| ArtDHTML provides a nifty digital clock that users can set the font style, spacing, and size for. And of course because you have the code you can also spiff it up. It uses CSS and setInterval(timer) as do most of our clocks.. | |
| English Clock by Adam Brown - provides an approximate reading of the current time. Its style is very, well English ,in the best sense of the word. | |

Advancing clock by JSMaster - allows users more control over time styling |
| Dynamic Drive and Kurt Grigg created the the Analog clock that floats in the lower right corner of this page | |
| CodeLifters are the good people who provided the Date + Time in the Title bar (or its down in the status bar if you are using an IE or NS 4 or earlier browser - shame shame). | |
Boy did we have fun trying to get all the clocks to work.
First, the old cross browser ugly reared its head in several instances of clocks
that demo nicely but don't want to work in a complete set of browsers -
IE5-8, NS?, Firefox, Opera, and Safari. The second problem we had was the interference
between
the setTimeout() and/or setInterval() commands between routines. Be sure to check to make sure all the variables are unique, ditto for CSS. For example,
we could get several clocks to work well on their own but then they did not
want to co-operate when on display with 2 or 3 other clocks. Now this latter case is an important matter because developers can easily
have more than one setTimeout() or set Interval() command if there any animations,
timings scripts, or timeout events. So be sure to check these potential JavaScript
timer conflicts carefully.
