time

Probably boring to most people but I created a tool to nail exactly 40 hours a week contracting using the laziest possible inputs getting me out as early as possible on Friday: https://github.com/cynoclast/time Usage example: tm 8.5 9.27 8.83 8.87 9:45-1:23 1:33- 14:11 54 minutes Notice you don't have to give it AM/PM? Also don't have to give it any flags. It figures out what to calculate based on number of arguments alone. And it knows 9:45 to 1:23 is around 4 hours, not -8. And during the week, decimal hours for timesheets: tm 8:30-12:30 12:40-6:40 10.0 I used it 5x a week during my contracting days.

I wrote a small program to manage my contracting time after it being gently suggested that I stick to 40 hours and that overtime wasn't needed of me (calculate hours per day and when to leave Friday to hit 40.0). I wrote it so that usage was absolutely as lazy as possible. So typical use cases look like this: >$ tm 8:30-12:30 12:40- Time to leave: 16:40 so as to hit 8.0 hours for the day. and >$ tm 8.5 9.27 8.83 8.87 9:45-1:23 1:33- 14:11 54 minutes is an example of when to leave (early!) on Friday to hit 40.0 Note how you don't have to tell it AM/PM or use 24 hour time. Nor give it any special flags to tell it which calculation to run. And it just handles the rollover at noon for you. source: https://github.com/cynoclast/time (Java, because that's what I used at the time)
