Is GMT the same as datetime?

With DateTime objects, the logic is the same. GMT is the model, and dates in all other time zones are representations. Apex actually makes this pretty easy for us — all DateTime objects we create are GMT DateTimes, but provide us a way to display it in any time zone. Just like our Distance class above which stores distance in millimeters, but can display it in any many different units.

Can you use datetime in GMT?

The answer is that you can’t. And in most cases, you don’t need to anyway. What you need from DateTime is to capture a moment in time, and every moment can be captured in GMT. Make sure that your DateTimes represent the correct moment in time, and you can always display it in any time zone.

Does DateTime always have GMT?

Almost everything discussed above becomes obvious if we follow just one principle: DateTime always has GMT as the model. You can construct a DateTime based on the local time zone (the time zone of the user) but it’s always saved as GMT.
