I was wondering if there's a way in Rails to calculate time stamp like - half a minute ago, 2 minute ago, 1 day ago etc. Something like twitter real time date stamp.
I want to know if Ruby/Rails has a built-in function for such date-time conversion?

You can just subtract 86400 from a Time object to get one day before. If you are using Rails, or have ActiveSupport included, you can replace 86400 with 1. days . If you're using a Date object, and not a Time object, just subtract 1 from it.
Ruby | DateTime now() function DateTime#now() : now() is a DateTime class method which returns a DateTime object denoting the given calendar date. Return: DateTime object denoting the given calendar date.
In your code above, simply replace d = DateTime. now with d = DateTime. new(2010,01,01, 10,00,00, Rational(-2, 24)). tt will now show the date d converted into your local timezone.
You can use:
10.minutes.ago
2.days.since
Or in your views you have the helpers:
distance_of_time_in_words(from_time, to_time)
time_ago_in_words(from_time)
Check the API for details and more options.

You can use available methods to get the time in past or future using ago, since alias for from_now and many available methods
Time.current

2.minutes.since

distance_of_time_in_words:
from_time = Time.now
distance_of_time_in_words(from_time, from_time + 50.minutes) # => about 1 hour
distance_of_time_in_words(from_time, 50.minutes.from_now) # => about 1 hour
distance_of_time_in_words(from_time, from_time + 15.seconds) # => less than a minute
distance_of_time_in_words(from_time, from_time + 15.seconds, include_seconds: true) # => less than 20 seconds
time_ago_in_words:
time_ago_in_words(3.minutes.from_now) # => 3 minutes
time_ago_in_words(3.minutes.ago) # => 3 minutes
time_ago_in_words(Time.now - 15.hours) # => about 15 hours
