Why people convert Singapore to MDT time

Scheduling a call from Singapore to MDT: a 10:00 AM start in Singapore lands at 8:00 PM in MDT the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -14h gap: Singapore and MDT have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in MDT is 7:00 PM in Singapore.
Booking travel or deliveries: tracking MDT local time against Singapore keeps pickup windows and arrival estimates honest across the -14h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM SGT" is unambiguous; "3 PM" across a -14h gap is not.
With a -14h gap there is no shared 9-to-5 window, so alternate the early start: one week Singapore takes the early slot, the next week MDT does.
