the error message means (most likely) that srOne[row, "timestamp"] has NA as a
value. Put
options(error = recover)
in your script so that you get control at the point of the error and can then
use 'browser' (?browser) to examine the values.
It is a problem with your data and probably the result of some calculation that
you will have to track down.
