hey how to convert string in timestamp

I recovered the text of time and I convert it in date

when I converted to timestamp the value is negative

var timenow=$("#time").text();
var res = timenow.split(":");
var d80 = new Date();
var curr_date = d80.getDate();
var curr_month = d80.getMonth();

var curr_year = d80.getFullYear();
var date1 = new Date(curr_date, curr_month, curr_year, res[0], res[1],res[2]);

console.log(date1);

const timestamp = date1 / 1000;
console.log(timestamp);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="time">
00:50:30
</div>

Call the date constructor in right way

new Date(year, monthIndex [, day [, hours [, minutes [, seconds [, milliseconds]]]]]);

var timenow=$("#time").text();
var res = timenow.split(":");
var d80 = new Date();
var curr_date = d80.getDate();
var curr_month = d80.getMonth();


var curr_year = d80.getFullYear();


var date1 = new Date(curr_year,curr_month, curr_date,res[0], res[1], res[2]);

console.log(date1); //"2019-10-26T01:20:00.000Z"


const timestamp = date1.getTime();// to get timestamp
console.log(timestamp);

let date2 = new Date(timestamp);
console.log(date2); //"2019-10-26T01:20:00.000Z"

Java: Convert String to TimeStamp, Follow these steps for a correct result: try { SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss.SSS"); Date parsedDate  Examples. The following example uses the Parse method to convert each element in a string array to a TimeSpan value. It changes the current system culture to Croatian - Croatia ("hr-HR") and English - United States ("en-US") to illustrate how the current system culture affects the parsing operation.

You're using the Date's constructor wrong. First parameter is the year:

var date1 = new Date(curr_year, curr_month, curr_date, res[0], res[1],res[2]);

Also, I think your code can be improved:

const [hours, minutes, seconds] = $("#time").text().split(":");

let currentDate = new Date();
currentDate.setHours(hours, minutes, seconds)

const timestamp = currentDate.getTime();
console.log(timestamp);

Convert between String and Timestamp, And when our String is in JDBC timestamp format – yyyy-m[m]-d[d] hh:mm:ss[.f…] – then it's pretty simple. We can interpret that pattern like this:  I want to convert a string to Timestamp. Here is the sample code. I want to parse the string to Timestamp.. I have tried to convert it like String date format is "18/01/11"; String date =

In JavaScript, a timestamp is the amount of milliseconds elapsed since 1 January 1970 (1 January 1970 is also known as Unix epoch time)

In your sample code date1 is 1931-04-11. Some 39 years before the epoch! Hence the negative value.

You need to use the correct format when constructing date1:

var date1 = new Date(curr_year, curr_month, curr_date, res[0], res[1],res[2]);

EG:

var timenow=$("#time").text();
var res = timenow.split(":");
var d80 = new Date();
var curr_date = d80.getDate();
var curr_month = d80.getMonth();

var curr_year = d80.getFullYear();
//var date1 = new Date(curr_date, curr_month, curr_year, res[0], res[1],res[2]);

var date1 = new Date(curr_year, curr_month, curr_date, res[0], res[1],res[2]);
console.log(date1);

const timestamp = date1 / 1000;
console.log(timestamp);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="time">
00:50:30
</div>

java.text.DateFormat.parse java code examples, ENGLISH); Date date = format.parse(string); Format for input SimpleDateFormat dateParser = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss "); // Parsing the date timestamp) { try { return DATE_FORMAT.parse(timestamp ).after(Calendar. The simplest way to parse a String to a Timestamp is its valueOf method: Timestamp.valueOf("2018-11-12 01:02:03.123456789") And when our String is in JDBC timestamp format – yyyy-m[m]-d[d] hh:mm:ss[.f…] – then it's pretty simple. We can interpret that pattern like this:

DateTime.ParseExact Method (System), dateString = "18/08/2015 06:30:15.006542"; format = "dd/MM/yyyy HH:mm:ss.ffffff" ; try { result = DateTime.ParseExact(dateString, format, provider); Console. Syntax – to_timestamp() to_timestamp(timestampString:Column) (or) to_timestamp(timestampString:Column,format:String) This function has above two signatures that defined in Spark SQL date functions, the first syntax takes just one argument and the argument should be in Timestamp format ‘MM-dd-yyyy HH:mm:ss.SSS‘, when the format is not in this format, it returns null.

How to convert seconds to time string format hh:mm:ss using , The Date() constructor expects a UNIX timestamp as one of its forms. A UNIX timestamp is a number of milliseconds that have passed since the epoch time (  TO_TIMESTAMP(timestamp, format) Arguments. The TO_TIMESTAMP() function requires two arguments: 1) timestamp. The timestamp is string that represents a timestamp value in the format specified by format. 2) format. The format for timestamp argument. To construct format strings, you use the template patterns for formatting date and time values.

Docs, Warning: Browser support for parsing strings is inconsistent. Because there moment('24/12/2019 09:15:00', "DD MM YYYY hh:mm:ss"); Note: Despite Unix timestamps being UTC-based, this function creates a moment object in local mode. Introduction One of the many common problems that we face in software development is handling dates and times. After getting a date-time string from an API, for example, we need to convert it to a human-readable format. Again, if the same API is used in different timezones, the conversion will be different. A good date-time library should convert the time as per the timezone. This is just one

Comments
  • but when i converted timestamp in date i did not find the same result
  • You should get timestamp by using date1.getTime() not dividing it by 1000
  • just I have last questions please how compare difference between 00:50:30 and anthoer variable for exemple 01:20:50
  • If you want to compare time then you can't just compare 01:20:50 and 00:50:30 cause they are strings if you compare them they will get lexicographically compared giving the wrong answer maybe it will work but that is not the correct way to compare time. You have to convert them into date objects like I did date1 and date2 then you can compare them using comparison operators. stackoverflow.com/questions/492994/…
  • There's a mistake the correct is var date1 = new Date(curr_year,curr_month, curr_date,res[0], res[1], res[2]);
  • thank you but when i converted timestamp in date i did not find the same result
