Usage of Dates and Times in Networked Applications


Terms and Expressions


Scenario / Problem

Scenario: Often networked applications have requirements such as:


A precise instant in time. E.g. the launch of Apollo 11.

Local Date

A date without zone information. E.g. this does not correspond to a specific instant in time.

E.g. your birthday. This contains no zone information even though at the instant when you were born, the date was not the same all over the globe (unlesss born at the exact time UTC 12:00:00).

E.g. if born in Denmark on February 7., 2020 at 21:00:00 (2020-02-07T21:00:00+01:00) the time in Australia is February 8., 2020 06:00:00 (2020-02-08T06:00:00+10:00). But nonetheless your birthday is February 7.
