cljs-time

Standard equality in Google Closure goog.date.* (and plain JavaScript Date objects) does not work the same way as in Joda/clj-time. Two date objects representing the same instant are not considered equal by default.

To perform equality checks, you have two options:

1. Use cljs-time.core/=.
2. Require the cljs-time.extend namespace, which extends goog.date.* datatypes so that standard clojure.core/= works as expected.

To use cljs-time in your project, add the following dependency to your Leiningen configuration. Note that version 0.5.* follows the API of clj-time 0.11.0.

If you are using Maven, you must first add the Clojars repository to your pom.xml:

<repository>
  <id>clojars.org</id>
  <url>http://clojars.org/repo</url>
</repository>

;; Leiningen dependency
[com.andrewmcveigh/cljs-time "0.5.2"]

The cljs-time.coerce namespace provides utilities to convert Google Closure DateTime instances to and from other types, such as JavaScript numbers (milliseconds) or ISO format strings.

(use 'cljs-time.coerce)

;; Convert DateTime to Unix epoch milliseconds (Long)
(to-long (date-time 1998 4 25))

;; Convert Unix epoch milliseconds to DateTime
(from-long 893462400000)

;; Convert an ISO format string to Unix epoch milliseconds
(to-long "2013-08-01")

Use cljs-time.format to convert date-time objects to strings (unparse) or strings to date-time objects (parse). Formatting is handled by formatter objects.

Formatter Syntax Notes:

• mm: minutes
• MM: months
• ss: seconds
• SSS: milliseconds

Use show-formatters to see a list of available built-in formatters.

(use 'cljs-time.format)

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

;; Parsing a string
(parse custom-formatter "20100311")

;; Unparsing a date-time to a string
(unparse custom-formatter (date-time 2010 10 3))

;; Get a moment at a specific time on the current date
(today-at 12 00)
