Overview
DateFormat.parse() returns a Date instance whose getTime() is always relative to GMT, regardless of the default JVM timezone or the timezone offset specified in the date string. For more details on DateFormat.parse() and timezone, see Java Time - Time Zone and DateFormat.
Samples
"yy/MM/dd hh:mm:ss,SSS a"
produces:
13/01/31 01:00:00,000 PM
Excel, CSV and milliseconds
Excel understands "." so you may want to:
13/01/31 01:00:00.000
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".
"T" in timestamp
If "T" shows in the timestamp, it can be specified as 'T' in format.
Example: "2016-08-03T13:54:39.464-0400" is parsed with:
new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSZ");
