用法
clj-time.core
The main namespace for date-time operations in the clj-time library is clj-time.core.
=> (require '[clj-time.core :as t]) Create a DateTime instance with date-time, specifying the year, month, day, hour, minute, second, and millisecond:
=> (t/date-time 1986 10 14 4 3 27 456) #<DateTime 1986-10-14T04:03:27.456Z> Less-significant fields can be omitted:
=> (t/date-time 1986 10 14) #<DateTime 1986-10-14T00:00:00.000Z> Get the current time with now and the start of the Unix epoch withepoch.
Once you have a date-time, use accessors like hour and second to access the corresponding fields:
=> (t/hour (date-time 1986 10 14 22)) 22 The date-time constructor always returns times in the UTC time zone. If you want a time with the specified fields in a different time zone, use from-time-zone:
=> (t/from-time-zone (t/date-time 1986 10 22) (t/time-zone-for-offset -2)) #<DateTime 1986-10-22T00:00:00.000-02:00> If on the other hand you want a given absolute instant in time in a different time zone, use to-time-zone:
=> (t/to-time-zone (t/date-time 1986 10 22) (t/time-zone-for-offset -2)) #<DateTime 1986-10-21T22:00:00.000-02:00>
