gots
gots is a crude UNIX timestamp manipulation CLI utility.
In addition to converting between human readable time/date format and UNIX timestamps, it also allows you to increment and decrement time by seconds, minutes, hours, days, months and years. Supports unix nanos.

Note that in order to convert dates from "string" format (ie. "01/02/2014 01:02:03"), the provided time format must match it exactly.
Accuracy
The generated timestamps can be a bit inaccurate - namely because I decided to not meddle with timezones, DST or any other time-related pains. This works for me, but may be a problem for you.
NOTE: I wrote this in 2015 when I just picked up Go :)
