#How to convert Unix Timestamp to Datetime in Ruby With example?

Time library provides methods to get current timestmap.

Time.now.to_i returns the current timestamp number. It is elapsed seconds since unix timestamp.

require 'time'

puts timestamp

There are two ways we can convert to Datetime.

• Time.at() method that returns Date time in Local timezone.
• DateTime.strptime method that returns Date time in UTC timezone.

use Time.at method Time class provides at method which takes argument of number and returns Date time in Local Format.

Here is an example code

require 'time'
require 'date'

# Get Current timestamp with now
timestamp=Time.now.to_i
puts timestamp
puts Time.at(timestamp)

Output:

1654736871
2022-06-09 01:07:51 +0000
2022-06-09T01:07:51+00:00

Another way using DateTime.strptime.

strptime method takes string parameter and formatted date and time in UTC Timezone

Here is an examples

require 'time'
require 'date'

# Get Current timestamp with now
timestamp=Time.now.to_i
puts timestamp

puts DateTime.strptime(timestamp.to_s,'%s')

Output:

1654736871
2022-06-09T01:07:51+00:00

#Convert Unix Timestamp to Date in Ruby

Convert this to Date using strftime() method with %d-%m-%y string format

Here is an example code

require 'time'
require 'date'

# Get Current timestamp with now
timestamp=Time.now.to_i
puts timestamp

puts DateTime.strptime(timestamp.to_s,'%s').strftime("%d-%m-%y")

Output:

09-06-22
