Trying to put daily tide information on a site. The date format that the
RSS feed uses is not recognized by pipes. I am wanting to convert the date
from RFC822 to ISO 8601 or some other format that is usable. Im wanting to
display the day's tides(i.e. Saturday) on Saturday. Presently it is
displaying two days ahead of time.
Thanks
