I have two date objects. One parsed from a server call in this form "2023-11-14T17:45:55Z" and a date object from adding minutes to .now.
I would like to write the code
serverDate > threeMinutesFromNow
But I want to be assured that this will work. I can't really find documentation on precisely HOW Date objects in swift implement comparable. If it's just by comparing timeIntervalSinceReferenceDate for the two AND that referenceDate is in a singular timezone I think this code is safe. But I am missing where I can check on this.
Date objects, themselves, simply do not have timezones.
2023-11-14T17:45:55Z, represents the same instant worldwide, i.e., 5:45pm UTC (aka GMT) on the 14th, whatever that is in your local timezone.
Date.now.addingTimeInterval(3 * 60) (or however you are creating
threeMinutesFromNow) represents a point in time worldwide. E.g., it is now 3:55pm in California, which is UTC-8, i.e., 11:55pm UTC; so 3 minutes from now is 11:58pm UTC.
So, using those example
Date objects, the
> operator will compare these two
Date objects, i.e., comparing 5:54pm UTC on the 14th to 11:58pm UTC today.
