Subject: nonstandard date time format?
Hi, All:
What functions exist for processing dates and times beyond, e.g.,
strptime? I can process the following examples using substr, paste,
strptime, etc., but I wonder if more elegant ways exist:
* " 90110134228 18800 105.3750 105.5000 105.3750"
records 4 numbers collected at 34228 seconds (9:30:28 AM) into 1
November 1990.
* " 40100 103.0900" is interpreted as a quantity of 103.9 on 4
January 2000.
* "1947 10 254.4" is 254.4 for October 1947.
* "1948 01 01 3.4" is 3.4 for 1 Jan. 1948
This is part of a soon-to-be released "FinTS" package companion to
Ruey Tsay (2005) Analysis of Financial Time Series (Wiley). Since this
is a teaching tool, I'd like to use the best approach available.
Otherwise, I'd just code something and move on to the next task.
Thanks,
Spencer Graves
