Shall help to concentrate in the office by synchronizing working times.
index.html is an example client. It runs with HTML, CSS, and JavaScript, querying every 40 seconds by AJAX and displaying the results.
eieruhr.php is the server. It works with PHP and delivers information upon request. It may be called with ?bus and will send the next busses leaving from UiT in addition to the other information. The number of busses depends on the Tromskortet API.
The response from the server is status;time_till_change;next_status;next_time_till_change;businfosouth;NORTH;businfonorth. status and next_status are either p (pause) or w (working) or u (unknown). time_till_change (and next_time_till_change) is the time until the next status change in seconds. businfosouth and businfonorth contain time|number|direction. time is the time when the bus is leaving in the format hh:mm:ss. number is the bus number and direction direction. South and north bound busses are separated by the signal word NORTH.
