A timer with two modes:
1. "in" - countdown a certain amount of time. Ex "5 hours"
This mode can be paused and resumed and the timer will pick up where it left off
2. "until" - countdown until a certain moment. Ex "13 august 2015 15:00"
In this mode, pausing only affects the display. Resuming the clock will skip to
maintain the correct end time.
