How do I get the number of seconds between two DateTimes in Ruby on Rails

Question

I\'ve got code that does time tracking for employees. It creates a counter to show the employee how long they have been clocked in for.

This is the current code:

Answer 1

Or, more readably:

diff = datetime_1 - datetime_2
diff * 1.days # => difference in seconds; requires Ruby on Rails

Note, what you or some other searchers might really be looking for is this:

diff = datetime_1 - datetime_2
Date.day_fraction_to_time(diff) # => [h, m, s, frac_s]
