Coordinated Universal Time

basically each place has a UTC plus or minus some number

that way people world wide can coordinate even if they live in different time zones

1630 utc -> 4:30 PM

if you live is UTC -2 then you rest 2 hours 2:30 PM at that's when the event will happen.

if you live UTC + 4 you add 4, so 8:30 PM

you can check which time zone you use locally easilly
