[R] add a data frame to my data frame

[Tagmarie]

Hello, 
Once again I feel so dumb. Can anyone help me? 
I have a data frame somewhat like that: 

myframe <- data.frame (ID=c("Ernie", "Ernie", "Bert", "Bert"),
Timestamp=c("24.09.2012 09:00", "25.09.2012 09:00", "24.09.2012 10:00",
"25.09.2012 10:00"), Hunger=c("1","1","2","2") )
myframestime <- as.POSIXct (strptime(as.character(myframe$Timestamp),
"%d.%m.%Y %H:%M"), tz="GMT")
myframe2 <- cbind (myframe,myframestime)
myframe2$Timestamp <- NULL 

Now I have a second dataframe with environmental variables. Something like
this: 

environ <- data.frame (ID=c("Ernie", "Ernie", "Bert"),
Timestamp=c("24.09.2012 09:00", "25.09.2012 09:00", "25.09.2012 10:00"),
Temp=c("25","30","27"), Rain =c ("0.1", "5", "2"))
envirotime <- as.POSIXct (strptime(as.character(environ$Timestamp),
"%d.%m.%Y %H:%M"), tz="GMT")
environ2 <- cbind (environ,envirotime)
environ2$Timestamp <- NULL

How do I merge or handle the two data frames at the respective lines so that
I get the data (Temp, Rain) at the correct line with (Hunger)?
