Maybe s_time and e_time are swapped here ?

Well, reading the Time documentation I see Time#to_f that may be a useful
number. And then, you could make a range with

s_time.to_f..e_time.to_f

Take note that comparisons on floats have their own problems
if the delta between them is very small and they are not integer.

1.9.3-p0 :001 > e_time = Time.now.utc
 => 2012-01-17 17:51:46 UTC
1.9.3-p0 :002 > s_time = e_time - 900
 => 2012-01-17 17:36:46 UTC

1.9.3-p0 :003 > range = s_time.to_f..e_time.to_f
 => 1326821806.2174225..1326822706.2174225

1.9.3-p0 :004 > log_time = Time.now.utc-300

Strange, obviously, for Float too ... (can't iterate from Float),
but, I can determine if a value is inside a range of Floats.
Why not for Time then ? Time has a <=> operator ...

I may have confused you even more ... (sorry for that).

I was under the impression you wanted to compare the lines
based on the string representation (in which case those issues
of midnight and mm/dd/yyyy representation etc. would play).

But if you import the date+time of each line with the code that
Robert proposed above, you end up with "clean" Time instances
that will work properly.

Sorry for the confusion ...

HTH,

Peter
