Time to Time is a simple calculator for working with times and durations.

Use it to quickly and easily find the duration between two times, add hours and minutes to a time, subtract hours and minutes from a time or any combination of these.

Time to Time tries to make calculations with times as easy as possible by having a familiar and quick to learn calculator interface.

Many different time formats are supported to speed up and simplify entering times, you don’t even need to enter am or pm for most times.

A 'now' button is also included to quickly add the current time to an expression.

Time to Time is great for freelancers, on-site technicians, businesses or just about anyone who wants to make working with times easier!

Example Usage
=============
- Calculate how many hours you worked today: 9 to 5 - 10 to 10:15 - 1h =
- Find out how much sleep you'll get between now and 7:30am: 'now' to 7:30am =
- Add up all of today's jobs: 9 to 10:13 + 10:45 to 11:30 + 2:30pm to 4:37pm =
- Add a list of time durations together: 1:13h + 2h + 0:15h + 28h + 17:45h =

Features
========
- Calculates the duration in days, hours and minutes from one time 'to' another time.
