Harvest/Jira worklog integration

Puts a button in Harvest that let's you log your harvest time directly into JIRA

This idea came up after wasting a lot of time moving the tracked time from harvest to JIRA tasks. You see, JIRA and Harvest measure time differently.

Here is an example:

Let's say you worked on a task for one hour and 6 minutes
- In harvest you would get something like: 1.10
- In JIRA you would have to calculate the equivalent of that number to the exact time, to get something like: 1h 6m

It get's pretty annoying, wasting time to calculate mere minutes, with this tool all you have to do is click two buttons and you're set. No more wasting time writing the time down.
