Comparing a DateTime with a Time in Ruby - Manchester Ruby on Rails Developer

For anyone that comes across this problem:

>> a = Time.now 
=> Wed Jun 23 13:50:35 +0100 2010 
>> b = DateTime.parse(a.to_s) 
=> Wed, 23 Jun 2010 13:50:35 +0100 
>> a 
=> Wed Jun 23 13:50:35 +0100 2010 
>> b 
=> Wed, 23 Jun 2010 13:50:35 +0100 
>> a == b 
=> false 
>> a.to_datetime == b 
=> false

The solution is to use ===

>> a.to_datetime === b 
=> true

From the docs:

Compares dates by Julian Day Number. When comparing two DateTime instances, or a DateTime with a Date, the instances will be regarded as equivalent if they fall on the same date in local time.
