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 DateFormat Timezone.

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".
