Suddenly the Kicksecure clock started showing the wrong time and the browser stopped working.
Please tell me how to fix it.
Thank you. It worked. 
There is also a bug related to timezone which is now fixed in git.

Will take time until it reaches stable repository. Options meanwhile: emulate that fix or set timezone to UTC.
