[R] NA instead of time stamp

[John Kane]

I think that you need to supply some data with your question.  

Use dput() to output your data or a subset of it and paste the output into the email
See ?dput for more information.

Probably a subset of the data would be sufficient.  Something like
dput(head(localRaw, 50) should be fine.
