Simply:

require 'time'

mT=Time.utc(2010,9,20,12,35,10,757)
=> Mon Sep 20 12:35:10 UTC 2010
mT1=Time.utc(2010,9,20,12,35,10,759)
=> Mon Sep 20 12:35:10 UTC 2010
mT1-mT
=> 2.0e-06

I would appreciate any help..

Alternative:

require 'time'

=> true

t1 = Time.parse("12:35:10.000757")

=> Mon Sep 20 12:35:10 +0100 2010

t2 = Time.parse("12:35:10.000759")

=> Mon Sep 20 12:35:10 +0100 2010

t2 - t1

=> 2.0e-06

If you got the ruby time, you can use the gem 'time_diff' to get the
time difference in a useful format like year, month, week, day, hour,
minute, second

I haven't looked at the gem, but....it's all just simple math, except
for the month part, which takes a bit more work. Does the gem
_actually_ calculate the difference in months between two dates, or
does it just approximate it?
