Thank you for the correction.

Indeed, because of the variable width on the milliseconds (1 to 3 digits),
you can have

12/31/2011 23:45:30:2

seemingly later than

12/31/2011 23:45:30:10

I believe that is not correct. It seems to be "milliseconds".

from http://ruby-doc.org/core-1.9.3/Time.html
the section "strftime( string ) =E2=86=92 string"


%L - Millisecond of the second (000..999)

%N - Fractional seconds digits, default is 9 digits (nanosecond)
          %3N  millisecond (3 digits)
          %6N  microsecond (6 digits)
          %9N  nanosecond (9 digits)
          %12N picosecond (12 digits)

HTH,

Peter
