get current date and time in groovy?

Question

What is the code to get the current date and time in groovy? I've looked around and can't find an easy way to do this. Essentially I'm looking for linux equivalent of date

I have :

import java.text.SimpleDateFormat

def call(){
    def date = new Date()
    sdf = new SimpleDateFormat("MM/dd/yyyy")
    return sdf.format(date)
}

but I need to print time as well.

Answer 1

Date has the time as well, just add HH:mm:ss to the date format:

import java.text.SimpleDateFormat
def date = new Date()
def sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss")
println sdf.format(date)

In case you are using JRE 8+ you can use LocalDateTime:

import java.time.LocalDateTime
def dt = LocalDateTime.now()
println dt

I had to add def or SimpleDateFormat before sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss") using Java 12 in a Gradle build file. – Kiushu

Answer 2

Date has the time part, so we only need to extract it from Date

I personally prefer the default format parameter of the Date when date and time needs to be separated instead of using the extra SimpleDateFormat

Date date = new Date()
String datePart = date.format("dd/MM/yyyy")
String timePart = date.format("HH:mm:ss")

println "datePart : " + datePart + "\ttimePart : " + timePart

A oneliner to print timestamp of your local timezone:

String.format('%tF %<tH:%<tM', java.time.LocalDateTime.now())

Output for example: 2021-12-05 13:20

How do you add the seconds? I tried '%tF %<tH:%<tM:%<tS' and '%tF %<tH:%<tM:%<ts' – Poona

Answering your question: new Date().format("MM/dd/yyyy HH:mm:ss")

                sdf = new SimpleDateFormat("MM/dd/yyyy")
                println(sdf.format(date))
                }
