Hello Jim
Thanx a lot.
Actually since long I was trying
> dts = c("1989-09-28", "2001-01-15", "2004-08-30", "1990-02-09")
> dts
[1] "1989-09-28" "2001-01-15" "2004-08-30" "1990-02-09"
> GMT = timeDate(dts, zone = "GMT", FinCenter = "GMT")
> GMT
GMT
[1] [1989-09-28] [2001-01-15] [2004-08-30] [1990-02-09]
> difftimeDate(GMT[1:2], GMT[-(1:2)])
Time differences in days
[1] -5450 3993
attr(,"tzone")
[1] "GMT"
*But the same was not working for 2008-09-12T23:48:07.747Z
Thank you very much*, *it worked*
Regards
Our Thoughts have the Power to Change our Destiny.
