[Bug] qremind uses specified TZ instead of UTC

[rtk-rnjn]

The bot uses IST converted time, which is good for comparing human like time delta with to datetime (in 2 minutes).

• When used times which matches ShortTime it localizes the datetime to IST (from UTC).
• "2m" should be 2 minutes from now, but it just - timdealta(hours=5, minutes=30) (+05:30 "IST")
