// Uses moment.js (installed as part of the build) to add a given amount of time
// to "now", and returns this as string. Invoke with a JSON containing:
//  - value: some number
//  - unit: some momentjs unit, as a string - e.g. days, d, hours, miliseconds
//
// For example, the following will add 3 hours to current time and return the response:
// {
//     "value": 3,
//     "unit": "hours"
// }
//
