I have the string which is formatted as below:

```
Tue Feb 11 12:28:36 +0000 2014

```

I try to convert this string to timestamps in R by using:

```
timeobj <- strptime(df[1], format = "%a %b %e %H:%M:%S %z %Y", tz = "GMT")

```

where df[1] is in format of `Tue Feb 11 12:28:36 +0000 2014`

However, I got an error as below:

```
Error in strptime(df[1], format = "%a %b %e %H:%M:%S %z %Y", tz = "GMT") : 
  input string is too long

```

How can I fix this?

```
dput(df[ 1:5, 1]) =

c("Tue Feb 11 12:47:26 +0000 2014", "Tue Feb 11 12:55:09 +0000 2014", "Tue Feb 11 13:22:29 +0000 2014", "Tue Feb 11 13:24:31 +0000 2014", "Tue Feb 11 13:34:00 +0000 2014") 

```
