This is a small web app I've been wanting to do for some time. Obviously this is very much inspired by others such as SunCalc and SunEarthTools. However I have tried to make a more interactve, configurable and mobile-friendly version with better time zone selection.
To move the sun-path diagram around, simply click and drag the location marker within the world map. It should be fast enough even on a phone or tablet to update in close to real time. You can also double-click or double-tap anywhere within the map to set the position expicitly.
If you intend using this for a particular project or in a demonstration, you can edit all the various app settings using the Cope/Paste as JSON... item in the menu and then copy/paste them into a text file. You can then load or drag/drop the file into the page whenever you need. You can also save the new settings as the default start-up values using the same menu.
The Shift and Ctrl/Meta keys are used pretty extensively to modify interactive data entry. This applies to all increment buttons, scroll wheel motion, slider controls and input elements.
NOTE: You can use the scroll wheel to edit a data value when hovering over any slider, numeric input or even table rows that indicate their editibility.
