You have been asked before (by me!) to give reproducible examples
using dput()...
You might need the diff() function.

Hi,
Does anyone know how to take a time difference when the format of the time
is as 13:22:23.586? I am trying to take the difference of time between stock
transactions and need to keep the three decimal places for seconds. I have
tried *diff(strptime(x, "%H:%M:%S.000))*, but apperantly that doesn

Try this:

Time difference of 228.9912 days

Dear R People:
I am looking at the ctime attribute of two different files. It
contains the year, month, day, time of creation and time zone.
Is there a way to determine the difference between the ctimes of two
files, please?
I looked in the chron package and nothing seemed to work.
Thanks in a
If what you have is a character string, then convert it to POSIXlt and
use difftime:

[1] "Wed Mar 18 12:18:11 2009"

[1] "Wed Mar 18 12:18:18 2009"

Dear all,
I have two variables which contents are date() function answers, like:
d1<-date()
d2<-date()
Now I need to compute the difference between d2 and d1 (in minutes).
Any help are welcome.

Hi,
I am computing some time differences.
Using the linux version of R 2.7.1
And I am getting a strange result ( see below )
I need the difference in minutes.
Actually looking for where it is NOT 15 minutes.
Would anyone know why this could be happening?
Or should I do this another way?
