This could be an embarrassingly easy question but I am new to Moment.js and fullcalendar.

**The goal:** Get fullcalendar to operate on a Moment/DateTime that is a few *minutes* offset from local computer time.

**The rationale:**
We want to synchronize the display time and nowIndicator with the old clocks in a building as opposed to the desktop's time. 

**Tried so far:**

```
// Get current offset:
var localOffset = moment().utcOffset();

// Shift by 7 minutes for illustration
localOffset -= 7;

// Set new offset for moment
moment().utcOffset(localOffset);

alert(moment().utcOffset());

```

As of now it prints back the original UTC offset and the nowIndicator matches my system clock. This is using Moment.js 2.19.0.

Thanks for looking.
