timestamp iso 8601

119. There are lots of differences between ISO 8601 and RFC 3339. Here is some examples to give you an idea: 2020-12-09T16:09:53+00:00 is a date time value that is compliant by both standards. 2020-12-09 16:09:53+00:00 uses a space to separate the date and time. This is allowed by RFC 3339 but not allowed by ISO 8601. ps 3 iso
