Technically, UTC is a time standard, and GMT is a time zone, so the two, although equal, are not really the same thing. Also, you can set your iPhone to UTC in the World Clock, which I do as an amateur astronomer.

I thought UTC the same, doesn't that mean that GMT+0 is essentially wrong? I thought GMT was essentially UTC+0, and all other time zones (ignoring DST) are defined as offsets to UTC, not GMT.

It's weird that the author chooses Iceland as an example of a GMT+0 country, rather than Britain which is where Greenwich is.

This is an old article since iOS has added UTC time zone to system settings and clock app. Android still doesn’t support UTC time zone, and need to use Iceland as hack. Which depends on Iceland not changing their time zone.

Had anyone here tried to live life with their iPhone on UTC?

We spent a lot of time at Yeshiva discussing when a Jew in space, or on Mars, or on a planet orbiting Alpha Centauri (for example) would have to light Shabbos candles or celebrate Yom Kippur.

This issue has already come up with Jewish astronauts on the Space Station.

I find it somewhat interesting that when SpaceX's streams switch to views with burned-in timecode it is always in UTC. Edit: and usually in ISO8601-ish format

If you are going to design something using a time code the most obvious solution is probably to choose your own zone. When you realize that doesn't apply to anyone else, UTC is the next option. Especially because it means you don't need to deal with user configuration.

As for ISO8601, that probably results from people looking for some standard to help with compatibility. If you just mean YYYY-DD-MM HH:MM that is just nicely ordered. Actual ISO8601 would yield something like: 2018-03-11T22:53:40+00:00 I personally really hate that T in ISO8601, but it is actually a standard aimed at being both human and machine readable.

All that aside, I think we can all agree that MM-DD-YYYY is just incongruous and stupid.

I don't have a phone, boss wants me to get one, & I'll be setting it to UTC if I end up with one

I've had my own devices set to UTC for the past few years. It made sense for coordinating when my friends are in whichever places of time, especially for online PvP gaming. It worked well when I was working remotely

Think of it as two pointers referencing the same data:

    Time* UTC = Time(0);
    Time* GMT = *UTC;

    *UTC == *GMT; // True
    UTC == GMT; // False

i read somewhere that some people may not like referring to britain as the default 'reference point' for timezones due to political/cultural reasons of their country. personally i dont have an issue with it, and i'm not saying that's the case here, maybe the author just likes iceland?

The UK developed the first portable timepiece good enough to accurately tell longitude. It's theirs.

The French didn't like it, but were outvoted. See:
