[R] Parsing a Date

[Philip]

Below is some Weather Service data.  I would like to parse the forecast date field into four different columns:

    Year
    Month
    Day
    Hour

I would like to drop the final four zeros.  Any suggestions?

forecast.date                 levels      lon           lat         HGT      RH          TMP       UGRD    VGRD
