clocks
is a very simple web application for creating and displaying multiple clocks using Simon Jones' SVG Clock and Mozilla's
localforage library.
Yes. There is a live demo that you can play with. There is also experimental offline-enabled demo if you're feeling adventurous.
Currently you will need to know the number of hours offset from UTC of the location you are creating a clock for. This is absolutely not a feature but all of the code and UI required to make that work as-if-like-magic is complicated enough that it's been saved for a future release. It's not ideal but that's how it is for now.
