What is the universal date format?

The ISO standard takes a general-to-specific approach for its date formats: The year comes first, followed by the month and then by the day of the month, with most elements represented as numerical values. For example, the ISO representation for July 15, 2022 is either 20220715 or 2022-07-15.

What is T and Z in time format?

What is T between date and time? The T is just a literal to separate the date from the time, and the Z means “zero hour offset” also known as “Zulu time” (UTC). If your strings always have a “Z” you can use: SimpleDateFormat format = new SimpleDateFormat( “yyyy-MM-dd'T'HH:mm:ss).

What is the difference between UTC and ISO?

Is ISO 8601 in UTC?
