Error in as.POSIXlt.character(as.character(x), ...) :
character string is not in a standard unambiguous format.
That error occurs when as.POSIXlt is looking for a format
with which to parse the strings. If you supply a format for the
date then as.POSIXlt will not give this error - it will
I have a dataframe that looks like the below. I want to convert the

properly formated and I get a message saying

Hello,

Hi. Thanks. Actually I don't know which ones are causing problems. I cannot
search through it because it is quite large (15 million records)

I just tried this:
z - strptime(radSampTrim$Captured.Time[1:30], %d%b%Y)
z[1:3]
[1] NA NA NA

Hello,
I think this should be
z - strptime(radSampTrim$Captured.Time[1:30], %F %T)

Yes! that worked.
By the way, still puzzled about how to write the function that would delete

Hello,
Maybe one possiblity is to search complete cases, such as
complete.cases(z), and subset according to the output.
It might also be interesting to check why you sometimes get NA.
