clj-time.format

Utilities for parsing and unparsing DateTimes as Strings.

Parsing and printing are controlled by formatters. You can either use one
of the built in ISO 8601 and a single RFC 822 formatters or define your own, e.g.:

  (def built-in-formatter (formatters :basic-date-time))
  (def custom-formatter (formatter "yyyyMMdd"))

To see a list of available built-in formatters and an example of a date-time
printed in their format:

 (show-formatters)

Once you have a formatter, parsing and printing are straightforward:

  => (parse custom-formatter "20100311")
  #<DateTime 2010-03-11T00:00:00.000Z>

  => (unparse custom-formatter (date-time 2010 10 3))
  "20101003"

By default the parse function always returns a DateTime instance with a UTC
time zone, and the unparse function always represents a given DateTime
instance in UTC. A formatter can be modified to different timezones, locales,
etc with the functions with-zone, with-locale, with-chronology,
with-default-year and with-pivot-year.

formatter

(formatter fmts)(formatter fmts dtz)(formatter dtz fmts & more)
Returns a custom formatter for the given date-time pattern or keyword.

formatter-local

(formatter-local fmt)
Returns a custom formatter with no time zone info.

formatters

Map of ISO 8601 and a single RFC 822 formatters that can be used for parsing and, in most
cases, printing.

members

(parse fmt s)(parse s)
Returns a DateTime instance in the UTC time zone obtained by parsing the
given string according to the given formatter.
parse-local
(parse-local fmt s)(parse-local s)
Returns a LocalDateTime instance obtained by parsing the
given string according to the given formatter.
parse-local-date
(parse-local-date fmt s)(parse-local-date s)
Returns a LocalDate instance obtained by parsing the
given string according to the given formatter.
parse-local-time
(parse-local-time fmt s)(parse-local-time s)
Returns a LocalTime instance obtained by parsing the
given string according to the given formatter.
show-formatters
(show-formatters)(show-formatters dt)
Shows how a given DateTime, or by default the current time, would be
formatted with each of the available printing formatters.
unparse
(unparse fmt dt)
Returns a string representing the given DateTime instance in UTC and in the
form determined by the given formatter.
unparse-local
(unparse-local fmt dt)
Returns a string representing the given LocalDateTime instance in the
form determined by the given formatter.
unparse-local-date
(unparse-local-date fmt ld)
Returns a string representing the given LocalDate instance in the form
determined by the given formatter.
unparse-local-time
(unparse-local-time fmt lt)
Returns a string representing the given LocalTime instance in the form
determined by the given formatter.
with-chronology
(with-chronology f c)
Return a copy of a formatter that uses the given Chronology.

with-default-year
(with-default-year f default-year)
Return a copy of a formatter that uses the given default year.
