purescript-now

Effect type and function for accessing the current machine's date and time.

Install now with Spago:

spago install now

The functions provided by now can be used to get the current date and time from the current machine's system clock.

Here are two example functions that print out the current year and time:

import Prelude
import Data.DateTime
import Data.Enum
import Effect
import Effect.Console
import Effect.Now

printCurrentYear :: Effect Unit
printCurrentYear = do
  currentDate <- nowDate
  let
    currentYear = fromEnum $ year currentDate :: Int
  log $ "The current year is " <> show currentYear

printCurrentTime :: Effect Unit
printCurrentTime = do
  currentTime <- nowTime
  let
    currentHour = fromEnum $ hour currentTime :: Int
    currentMinute = fromEnum $ minute currentTime :: Int
  log $ "The current time is " <> show currentHour <> ":" <> show currentMinute

We can then try these functions out in a REPL:

> printCurrentYear
The current year is 2021

> printCurrentTime
The current time is 1:54
