most common json timestamp format

The most common JSON timestamp formats are:

1. ISO 8601 Format: This is widely accepted and recommended for representing dates and times in JSON. It follows the pattern "YYYY-MM-DDTHH:mm:ss.sssZ", where:
   • "YYYY" represents the year.
   • "MM" represents the month.
   • "DD" represents the day.
   • "T" separates the date and time.
   • "HH" represents the hour.
   • "mm" represents the minute.
   • "ss" represents the second.
   • "sss" represents milliseconds.
   • "Z" indicates UTC time or includes a time zone offset (e.g., "+/-HH:mm")¹²³.

Example: "2023-08-20T13:20:10.633Z"

2. Unix Timestamp Format: This represents the number of seconds or milliseconds since January 1, 1970, 00:00:00 UTC. It is often used for efficient date manipulation and calculations¹²⁴.

Example: 1699027592000 (milliseconds) or 1641043200 (seconds)

Both formats are widely used, but ISO 8601 is generally preferred for its readability and standardization across different systems.
