Question

What is the meaning of T in this datetime pattern ?

yyyy\'-\'MM\'-\'dd\'T\'HH\':\'mm\':\'ss 2011-06-14T04:12:36

Answer 1

It just shows the start of the Time component in a standard ISO 8601 date time string. Wikipedia has a detailed page about this standard format.

Answer 2

Without some context, that's hard to answer.

However, according to the SimpleDateFormat JavaDoc 'T' is meaningless i.e. just a string literal.

This is supported by the fact the T is visible in your output string. Perhaps it means time?

Answer 3

it means "Time". this has been asked and answered a lot. see http://www.w3.org/TR/NOTE-datetime.html

Answer 4

In ISO 8601 (UTC) T is used to designate the Time component. See "Combined date and time representations" in http://en.wikipedia.org/wiki/ISO_8601#Combined_date_and_time_representations

Answer 5

[T] is time designator for ISO 8601 format of <date>T<time>.

Answer 6

It's from ISO 8601 which specifies a standard timestamp format:

The character [T] shall be used as time designator to indicate the start of the representation of the time of day component in these expressions.
