Why people convert GST to São Paulo time

Scheduling a call from GST to São Paulo: a 10:00 AM start in GST lands at 3:00 AM in São Paulo, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both GST and São Paulo are inside the 9-to-5 working day between 4:00 PM and 5:00 PM GST time (9:00 AM–10:00 AM BRT). That is roughly 1 hours of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in GST is 1:00 PM in São Paulo makes it easy to avoid calling at 3 AM.
