Well, looking at the code you've provided showing what you've tried so far . . .

Oh, you didn't. Never mind.

Read the line. Extract the timestamp. Parse the timestamp (see Date::Manip, Date::Calc). Compare with now. Print if it's within your window.

Update:

require 'time'

now=Time.now

ARGF.each do |line|
  next unless line =~ /(.*?) : Depth/
  d_days = ( now - Time.parse( $1 ) ) / 86400
  puts line if d_days < 45
end
