Why London is 4-5 hrs ahead and LA is 3 hrs behind Boston though both are as far

Are links to reddit comment threads really worth posting here. What's next, links to Nextdoor commentary?

OP has a misleading premise, and the top comment thread is focusing on a less relevant detail. More relevant comments focus on the longitude, rather than the straight-line distance.

> Los Angeles is about 47° longitude from Boston, and London is about 71° longitude from Boston.

Yeah, they should really be complaining about Lima, Peru!

Because time-zones are based on regions and borders, not by degrees on a globe.

An example for economic "region" would be the northwest county of Indiana which is the same time zone as Chicago, one state over in Illinois, while Indiana is otherwise one hour ahead.

Didn't Indiana transition to be all in the same time zone recently?

China is the worst offender. It must be terrible during winter when you live on the far western side of the country, and the sun rises at noon or something :/

What do you mean? The sun always shines while the great Xi Jinping is in power.
