If you are using 'difftime', you can specify the units:
x <- as.POSIXct(c('2009-01-01 10:00', '2009-03-04 13:00'))
x
[1] "2009-01-01 10:00:00 GMT" "2009-03-04 13:00:00 GMT"
Time difference of 62.125 days
difftime(x[2], x[1], units='secs')
Time difference of 5367600 secs

Dear R-Experts,
Seek your help.
In a List object e.g. Time_duration[[]], I am storing differece between
two
time-stamps (start-time and end-time) for a certain event.
Time difference does not remain constant for, say, 10 observations.
Each time, the time difference is given in different time units: seconds
/
hours / minutes.
Can you please tell me - how I can store the values of time difference in
just one time unit ?
It can be either seconds, or minutes or hours. The criterion is - unit
should be consistent.
Thank you in advance.
Regards,
Suresh
