How to Get the Current Time

How do I get the current time?

Use datetime:

>>> import datetime
>>> now = datetime.datetime.now()
>>> now
datetime.datetime(2009, 1, 6, 15, 8, 24, 78915)
>>> print(now)
2009-01-06 15:08:24.789150

For just the clock time without the date:

>>> now.time()
datetime.time(15, 8, 24, 78915)
>>> print(now.time())
15:08:24.789150

To save typing, you can import the datetime object from the datetime module:

>>> from datetime import datetime

Then remove the prefix datetime. from all of the above.

How to get the current date/time in Java

It depends on what form of date / time you want:

If you want the date / time as a single numeric value, then System.currentTimeMillis() gives you that, expressed as the number of milliseconds after the UNIX epoch (as a Java long). This value is a delta from a UTC time-point, and is independent of the local time-zone¹.
If you want the date / time in a form that allows you to access the components (year, month, etc) numerically, you could use one of the following:
- new Date() gives you a Date object initialized with the current date / time. The problem is that the Date API methods are mostly flawed ... and deprecated.
- Calendar.getInstance() gives you a Calendar object initialized with the current date / time, using the default Locale and TimeZone. Other overloads allow you to use a specific Locale and/or TimeZone. Calendar works ... but the APIs are still cumbersome.
- new org.joda.time.DateTime() gives you a Joda-time object initialized with the current date / time, using the default time zone and chronology. There are lots of other Joda alternatives ... too many to describe here. (But note that some people report that Joda time has performance issues.; e.g. https://stackoverflow.com/questions/6280829.)
- in Java 8, calling java.time.LocalDateTime.now() and java.time.ZonedDateTime.now() will give you representations² for the current date / time.

Prior to Java 8, most people who know about these things recommended Joda-time as having (by far) the best Java APIs for doing things involving time point and duration calculations.

With Java 8 and later, the standard java.time package is recommended. Joda time is now considered "obsolete", and the Joda maintainers are recommending that people migrate.³.

^{1 - System.currentTimeMillis() gives the "system" time. While it is normal practice for the system clock to be set to (nominal) UTC, there will be a difference (a delta) between the local UTC clock and true UTC. The size of the delta depends on how well (and how often) the system's clock is synced with UTC.

2 - Note that LocalDateTime doesn't include a time zone. As the javadoc says: "It cannot represent an instant on the time-line without additional information such as an offset or time-zone."
3 - Note: your Java 8 code won't break if you don't migrate, but the Joda codebase may eventually stop getting bug fixes and other patches. As of 2020-02, an official "end of life" for Joda has not been announced, and the Joda APIs have not been marked as Deprecated.}

How to get the current time with python

from datetime import datetime

print(datetime.now().strftime("%H:%M"))

Will return this:

13:29

To get seconds too:

print(datetime.now().strftime("%H:%M:%S"))

How to get current time and date in Android

You could use:

import java.util.Calendar;
import java.util.Date;

Date currentTime = Calendar.getInstance().getTime();

There are plenty of constants in Calendar for everything you need.

Check the Calendar class documentation.

How do I get the current time only in JavaScript

var d = new Date("2011-04-20T09:30:51.01");
d.getHours(); // => 9
d.getMinutes(); // =>  30
d.getSeconds(); // => 51

var d = new Date(); // for now
d.getHours(); // => 9
d.getMinutes(); // =>  30
d.getSeconds(); // => 51

Getting current date and time in JavaScript

.getMonth() returns a zero-based number so to get the correct month you need to add 1, so calling .getMonth() in may will return 4 and not 5.

So in your code we can use currentdate.getMonth()+1 to output the correct value. In addition:

.getDate() returns the day of the month <- this is the one you want
.getDay() is a separate method of the Date object which will return an integer representing the current day of the week (0-6) 0 == Sunday etc

so your code should look like this:

var currentdate = new Date(); 
var datetime = "Last Sync: " + currentdate.getDate() + "/"
                + (currentdate.getMonth()+1)  + "/" 
                + currentdate.getFullYear() + " @ "  
                + currentdate.getHours() + ":"  
                + currentdate.getMinutes() + ":" 
                + currentdate.getSeconds();

JavaScript Date instances inherit from Date.prototype. You can modify the constructor's prototype object to affect properties and methods inherited by JavaScript Date instances

You can make use of the Date prototype object to create a new method which will return today's date and time. These new methods or properties will be inherited by all instances of the Date object thus making it especially useful if you need to re-use this functionality.

// For todays date;
Date.prototype.today = function () { 
    return ((this.getDate() < 10)?"0":"") + this.getDate() +"/"+(((this.getMonth()+1) < 10)?"0":"") + (this.getMonth()+1) +"/"+ this.getFullYear();
}

// For the time now
Date.prototype.timeNow = function () {
     return ((this.getHours() < 10)?"0":"") + this.getHours() +":"+ ((this.getMinutes() < 10)?"0":"") + this.getMinutes() +":"+ ((this.getSeconds() < 10)?"0":"") + this.getSeconds();
}

You can then simply retrieve the date and time by doing the following:

var newDate = new Date();
var datetime = "LastSync: " + newDate.today() + " @ " + newDate.timeNow();

Or call the method inline so it would simply be -

var datetime = "LastSync: " + new Date().today() + " @ " + new Date().timeNow();

How to get current time in python and break up into year, month, day, hour, minute?

The datetime module is your friend:

import datetime
now = datetime.datetime.now()
print(now.year, now.month, now.day, now.hour, now.minute, now.second)
# 2015 5 6 8 53 40

You don't need separate variables, the attributes on the returned datetime object have all you need.

How to get the current time as datetime

Update for Swift 3:

let date = Date()
let calendar = Calendar.current
let hour = calendar.component(.hour, from: date)
let minutes = calendar.component(.minute, from: date)

I do this:

let date = NSDate()
let calendar = NSCalendar.currentCalendar()
let components = calendar.components(.CalendarUnitHour | .CalendarUnitMinute, fromDate: date)
let hour = components.hour
let minutes = components.minute

See the same question in objective-c How do I get hour and minutes from NSDate?

Compared to Nate’s answer, you’ll get numbers with this one, not strings… pick your choice!

How to get the current time?

It doesn't give you back a function, it is a function.

Try some other functions and the output is very similar:

- List.hd;
val it = fn : 'a list -> 'a
- String.str;
val it = fn : char -> string

Time.now is a function from unit to Time.time.

The only value of the type unit is written () (which is also called "unit"), so you call it like this:

- Time.now ();
val it = TIME {usec=1516525299967615} : Time.time

Get the current time in C

Copy-pasted from here:

/* localtime example */
#include <stdio.h>
#include <time.h>

int main ()
{
  time_t rawtime;
  struct tm * timeinfo;

  time ( &rawtime );
  timeinfo = localtime ( &rawtime );
  printf ( "Current local time and date: %s", asctime (timeinfo) );
  
  return 0;
}

(just add void to the main() arguments list in order for this to work in C)
