Minute Difference

Hi,

Here i have a time along with date,
for eg:-  "10/5/2012 5:05:00 AM"

i need to do minus 10 minutes along current date
Like this :- "10/5/2012 4:55:00 AM"

There are both 'cut' and 'seq' methods for vectors of class POSIXt. These support operations that specify particular units. 

?cut.POSIXt  # has link to the seq method help page

I am not posting code when questions fail to adhere to the reproducible code request.

Hi,
Try this:
date1<-"10/5/2012 5:05:00 AM" 

?format(as.POSIXct(strptime(date1,format="%m/%d/%Y %H:%M:%S"))-600,format="%m/%d/%Y %r")
#[1] "10/05/2012 04:55:00 AM"

A.K.

Hi Antony,
Did you get an answer for this?

oldtime<-strptime("10/5/2012 5:05:00 AM",
  format="%d/%m/%Y %I:%M:%S %p")
oldtime
[1] "2012-05-10 05:05:00"
# now subtract 10 minutes (600 seconds)
oldtime - 600
[1] "2012-05-10 04:55:00 EST"
