JSON (JavaScript Object Notation) is a lightweight data interchange format that is used for exchanging data between a server and a web application. In JSON, date-time values are usually represented as strings in the ISO 8601 format, which is a standardized format for representing date-time values.
For example, a date-time value of February 9th, 2023, at 5:30 PM might be represented in JSON as follows:
"2023-02-09T17:30:00Z"
Note that the "T" in the string above is used to separate the date and time portions of the value, and the "Z" at the end of the string indicates that the time is in the UTC time zone. This format allows for easy and consistent parsing of date-time values in a variety of programming languages.
