Answer 1

if "Event (No 3) 0007141706 at 2010/04/27 11:48 ( Pacific )" =~ /\d{4}\/\d{2}\/\d{2} \d{2}:\d{2}/
  puts "Date and time found."
end

This will check if your string contains a date and time in the specified format.

It does however only check the amount of digits, so a string containing 2010/13/99 93:71 would be equally valid. Which it is not.
