Hello! Someone knows how to get the current time from OS using Joker?
gleisonsilva 2020-01-11T14:16:15.001500Z
(i mean... without calling a shell or another executable in OS...)

See the joker.time namespace.

I've seen, but I couldn't figure out. When I call joker.time/now I get back a #object[Proc] that I couldn't use in any place...
gleisonsilva 2020-01-11T14:38:55.003900Z
I've tried call string, parse, etc on it, but uncessfully
jcburley 2020-01-11T14:47:52.004900Z
A Proc is just an internally compiled Fn. I.e. you call it.

gleisonsilva 2020-01-11T14:53:34.005400Z

thank u

And it doesn't return just a String, but a Time object that you can further manipulate:
user=> (type (joker.time/now))
Time
user=> (joker.time/now)
2020-01-11 09:54:15.601988473 -0500 EST m=+9.694898411
user=> (let [cur (now)] (sleep (* second 3)) (println (sub (now) cur)))
3000091841
nil
user=> jcburley 2020-01-11T15:01:04.007200Z
(Forgot to show the (use 'joker.time) in there before the (let ....)
