Use the utc() method of moment to remove the timezone and display everything in universal time.
moment.utc('2015-01-22T16:11:36.36-07:00').format('l LT')
That will display the time as it is in UTC without any timezone offset. If you want to display the time as it was recorded in the user/server timezone you can parse the zone information when you construct a moment instance and have it use the timezone recorded in the parsed string.
moment.parseZone('2015-01-22T16:11:36.36-07:00').format('l LT');
With either of these approaches you should consider labeling the time in some way to reflect the timezone the time corresponds to. Failing to do this could lead to a lot of confusion for the end users.
