Re: clj-time/do-at not workin as expected

[JvJ]

Actually, I've been using async channels the whole time.  I just wanted to 
use scheduling rather than timeouts if possible.  So, I'd like to be able 
to say "wait until this time" instead of "wait for an amount of time".

Have you considered using async channels?

Chime seems great, but I'm looking for something cross-platform (java/js).

Ooooh, now I get it.  Is there something equivalent do the kind of delayed 
operation I'm expecting?

Re: clj-time/do-at not workin as expected

[Sean Corfield]

The docstring could be clearer…

 

The do-at macro (which uses the do-at* function), evaluates the expression in 
the context of the time being what you specified. Mostly useful for testing I 
suspect:

 

boot.user=> (t/do-at (-> 1 t/minutes t/from-now) (println "Hi!" (t/now)))

Hi! #object[org.joda.time.DateTime 0x169f53b5 2016-05-20T03:20:53.021Z]

nil

boot.user=> (t/now)

#object[org.joda.time.DateTime 0x11798c1b "2016-05-20T03:19:54.145Z"]

 

See how the time printed is a minute in the future of the actual time?

SUP

;; => nil

 

In the above example, "SUP" is printed instantaneously, even before the return 
value of do-at* is printed.

 

Is this a bug, or is there some other reason for it?

clj-time/do-at not workin as expected

[JvJ]

Whenever I call do-at or do-at*, the result expression is executed 
immediately instead of at the specified time.

specs.core> (tm/do-at* (-> 30 tm/seconds tm/from-now) (fn [] (println 
"SUP")))
SUP
;; => nil


In the above example, "SUP" is printed instantaneously, even before the 
return value of do-at* is printed.

Is this a bug, or is there some other reason for it?
