searchTwitter timestamps - r

Question

I am using the twitteR library in R and wondering if is is possible to get timestamps associated with a search or a timeline for that matter. E.G if searching #rstats using searchTwitter, I would like to know when the tweets were made...are there additional parameters I need to parse in order to get that information?
here is some example code...
library(twitteR)
searchTwitter("#rstats",n=10)
giving the following result
[[1]]

Answer 1

after a google:
mytweet <- searchTwitter("#chocolate",n=10)
str(mytweet[[1]])
Reference class 'status' [package "twitteR"] with 10 fields
$ text : chr "The #chocolate part of the #croquette. #dumplings #truffles http://t.co/Imwt3tTP"
$ favorited : logi FALSE
$ replyToSN : chr(0)
$ created : POSIXct[1:1], format: "2013-01-27 16:26:03"
$ truncated : logi FALSE
$ replyToSID : chr(0)
$ id : chr "295568362526896128"
$ replyToUID : chr(0)
$ statusSource: chr "<a href="http://instagr.am">Instagram</a>"
$ screenName : chr "tahiatmahboob"
and 33 methods, of which 22 are possibly relevant:
getCreated, getFavorited, getId, getReplyToSID, getReplyToSN, getReplyToUID, getScreenName, getStatusSource, getText, getTruncated,
initialize, setCreated, setFavorited, setId, setReplyToSID, setReplyToSN, setReplyToUID, setScreenName, setStatusSource, setText,
setTruncated, toDataFrame
So time stamp is:
mytweet[[1]]$created
[1] "2013-01-27 16:26:03 UTC"
Never used twitteR until I read your question. Seems like something fun to do when bored.

Answer 2

One alterantive to parse the result( as the answer above) , is to use argument since and until.
For example you can do :
res <- searchTwitter("#rstats",n=1000,since='2013-01-24',
until='2013-01-28')
The searchTwitter is a wrapper to the JSON API of twitter. Take a look here for more details of the argument and example of the JSON results.
