* R/times.R (trunc.times):
* man/trunc.times.Rd:
New trunc() methods for times objects, donated by Gabor
Grothendieck <ggrothendieck@gmail.com>.
2005-10-25 Kurt Hornik <Kurt.Hornik@wu-wien.ac.at>
* DESCRIPTION (Version): New version is 2.3-0.
* R/times.R ("Axis.times"): New Axis() method for R 2.3.0 or
better, suggested by G Grothendieck <ggrothendieck@gmail.com>.
("plot.times"): Use 'col.axis' rather than 'col' etc for catching
graphical parameters in ... that affect (and are passed to)
axis(). Spotted by Parlamis Franklin <fparlamis@mac.com> and
relayed by Marc Schwartz <MSchwartz@mn.rr.com>.

2005-04-28 Kurt Hornik <Kurt.Hornik@wu-wien.ac.at>
* DESCRIPTION (Version): New version is 2.2-35.
* R/chron.R:
* R/dates.R:
* R/times.R:
* R/utils.R:
As spotted by David Harte <david@statsresearch.co.nz>, there is a
problem with dates before the origin:
R> chron(dates.="12/31/1969", times.="18:00:00")
[1] (01/01/70 -06:00:00)
(Most likely not as intended.) Fix by changing trunc() to floor()
when extracting dates and times parts.
2005-02-26 Kurt Hornik <Kurt.Hornik@wu-wien.ac.at>
* DESCRIPTION (Version): New version is 2.2-34.
* R/dates.R (seq.dates): Two patches suggested by Steve Su
<s.su@qut.edu.au> and relayed by Martyn Plummer
<plummer@iarc.fr>.
2004-11-06 Kurt Hornik <Kurt.Hornik@wu-wien.ac.at>
* DESCRIPTION (Version): New version is 2.2-33.
* R/dates.R (seq.dates): seq.dates(by = "months") was wrong for
end of month dates. Spotted by Ciprian_Marin@ssga.com, fix by
Gabor Grothendieck <ggrothendieck@myway.com>. See also message
2004-November/058829.html in the r-help mail archive at
https://www.stat.math.ethz.ch/pipermail/r-help/.
2004-09-15 Kurt Hornik <Kurt.Hornik@wu-wien.ac.at>
* DESCRIPTION (Version): New version is 2.2-32.
* R/dates.R (seq.dates): seq.dates() gave too many months/years if
a given length was too large. Trim back to the specified length
(spotted by <Scott.Waichler@pnl.gov>, fix suggested by Gabor
Grothendieck <ggrothendieck@myway.com>).
2004-05-28 Kurt Hornik <Kurt.Hornik@wu-wien.ac.at>
* DESCRIPTION (Version): New version is 2.2-31.
* R/utils.R ("is.holiday", "is.weekend"): If the argument does not
inherit from dates, try coercing to chron. The is.numeric() test
does not do the right thing for POSIXct objects (e.g., obtained by
Sys.time(), spotted by Matthew Dowle <mdowle@concordiafunds.com>).
* man/is.holiday.Rd: Document the above change.
* R/dates.R ("Ops.dates"): At least avoid duplicated class
entries.

Fix codoc default value mismatch problems.
2003-07-16 Kurt Hornik <Kurt.Hornik@wu-wien.ac.at>
* DESCRIPTION (Version): New version is 2.2-27.
(Depends): Need R 1.6.0 or better, as src/init.c uses
R_NativePrimitiveArgType.
2003-06-28 Kurt Hornik <Kurt.Hornik@wu-wien.ac.at>
* DESCRIPTION (Version): New version is 2.2-26.
* man/chron.Rd: Explicitly say that for day/month/year format
specifications, the separator must be non-null. Thanks to Jerome
Asselin <jerome@hivnet.ubc.ca> for the suggestion and the PRs for
the previous release.
2003-06-25 Kurt Hornik <Kurt.Hornik@wu-wien.ac.at>

2001-11-27 Kurt Hornik <Kurt.Hornik@ci.tuwien.ac.at>
* DESCRIPTION (Version): New version is 2.2-19.
* R/chron.R:
* R/dates.R:
* R/times.R:
.Alias() is gone in R 1.4.0, hence remove.
2001-09-18 Kurt Hornik <Kurt.Hornik@ci.tuwien.ac.at>
* DESCRIPTION (Version): New version is 2.2-18.
* R/chron.R (chron): the default for the argument `out.format' was
wrong if the argument `format' was a function or R symbol (in
these cases `out.format' now is not set and we stop). As the
current code does not always preserve format slots, we need to
make a NULL format correspond to the default.
* R/dates.R (convert.dates): now correctly handles formats given
as R symbols.
* R/times.R (convert.times): now correctly handles formats given
as R symbols.
* R/utils.R (month.day.year): now coerces its argument to be
integer since the algorithm requires integer arithmetic.
All fixes by David James.

sec (suggested by BDR).
