Will guy that execute this in US see the same number with the guy doing this in US if they both do it at the same time?
The documentation says it’s the time starting at 1 January 2001 GMT. That means it’s from the time GreenWitch reach 1 January.
However, each people would see a different clock. So that means it’s localized.
So it’s ambiguous. Which one is right?
NSDatedoes not store time zone information. It is always relative to GMT/UTC time, which means both the people you describe will get back the same result.
