What is this datetimestamp 20220914171900Z-0700 in JSON?

I see below datetimestamp in json but not sure which format is this??

20220914171900Z-0700

any suggestions??

Thanks in advance!

I used constructDateString but no luck!

>Solution :

• 2022 – yyyy (Year)
• 09 – MM (Month)
• 14 – dd (day of month)
• 17 – HH (Hour of day)
• 19 – mm (Minute of hour)
• 00 – ss (Second of minute)
• Z-0700 – Z stands for Zulu and represents 00:00 hours offset from UTC. So, Z-0700 means an offset of 07:00 hours from UTC. If you want to get this date-time at UTC, you can do so by adding 07:00 hours to 2022-09-14T17:19.

Demo using Java:

import java.time.OffsetDateTime;
import java.time.ZoneOffset;
import java.time.format.DateTimeFormatter;

class Main {
    public static void main(String[] args) {
        DateTimeFormatter dtf = DateTimeFormatter.ofPattern("uuuuMMddHHmmss'Z'Z");
        String strDateTime = "20220914171900Z-0700";
        OffsetDateTime odt = OffsetDateTime.parse(strDateTime, dtf);
        System.out.println(odt);

        // The same date-time at UTC
        OffsetDateTime odtUTC = odt.withOffsetSameInstant(ZoneOffset.UTC);
        System.out.println(odtUTC);
    }
}

Output:

2022-09-14T17:19-07:00
2022-09-15T00:19Z

Note: You can use y instead of u here but I prefer u to y.
