Date ranges made easy

Several of the MSP API require a timespan in epoc format. I wrote a script to subtract a number minutes and hours before the current time and now and present both in epoc format. This gives you a "start" and "end" time for the APIs. 

$ epocdate.sh 
How many minutes before now?
10
You entered 10 minutes


How many hours before now?
24
You entered 24 hours

I might change this so that the end time can be calculated as well if there's any interest.
