How to convert timestamp to readable format in blockchain info

Question

I need some help with Blockchain API timestamps. The timestamps from the JSON responses are not user readable. I need to parse this to a readable format to run some logical function based on time. 

The timestamp looks something like this:

"time": 1331300839,

I tried to do something like this:

var test = new Date(1331300839);
test.getFullYear();

This is not working. How can I convert the timestamp to a readable format?

Answer 1

You are talking about the block_time property of the block. The block_time is in Unix time format. A quick way to convert this without using any library is by running it through the date command.

Something like this:

$ date -d @1395103695

Hope this helps!

This works! The date is returned in the following format:

<Day> <Month> <Date> <Time> <Standards> <Year>

Hey. This is not working for me. I am using Mac OSX and this command is not working. Any alternatives for Mac OSX?

Try this for Mac:

$ date -j -f "%s" 1395103695

Try using the moment.js library. The code will look something like this:

var time = moment.unix(1331300839)

And then convert to parsed data to string using moment.toString():

time.toString()
// "Fri Sep 03 2018 10:23:19 GMT+0100"

The date is not actually in a non-readable format, it's just in a different readable format. The data you mentioned in the question is the data in milliseconds. So, you can use that value and convert it into the data by multiplying it with 1000. Try something like this:

var test = new Date(1331300839*1000);
alert(test.getFullYear());
