Re: Tide article

Chuck,
I chickened for the time being, after making over the
Day of Month Num, Day Code, 12 hour clock time, AM/PM, from
NOAA into a form that I could easily input to NLReg,
which was
day number formatted at e.g. day 5 for a.m,
and day 5.5 for the pm times,
removing text fields, and processing this to a cumulative minute
count for each tidal event in the month.

It is this monotonic time series, that would be helpful for an FFT,
even if slightly tedious to generate without a smart editor here.
