Hour in Day

Warning If not using AM/PM (no "a" in the format), make sure you use HH for hours (instead of hh).

According to the documentation:

• "h" - Hour in am/pm (1-12)
• "H" - Hour in a day (0-23)

Month

To parse "Sep" use "MMM".

To parse "09" use "MM".

DateFormat and timezone

java DateFormat and Timezone

Time Zone

Z

for -0800

Just one single "Z" not four or five.

UTC

Use Time Zone (see above) and "0000".

Examples:

This is UTC.

15/01/01 01:01:01+0000

This is PDT.

15/01/01 01:01:01-0700

Z in Time Stamp

"Z" means GMT in ISO 8601

To parse that, add "X" in the pattern.

"2015-09-22T18:03:46Z" is parsed by "yyyy-MM-dd'T'HH:mm:ssX"
