Returns Julian day counts, date/time atoms from a "timeDate"
object,
and extracts month atoms from a "timeDate"
object.

for julian
, a difftime
object;
for atoms
, a data.frame
with attribute "control"
containing the financial center of the input vector x
. The
data frame has the following components:
year,
month,
day,
hour,
minute,
scond;
for months
, a numeric vector with attribute "control"
containing the financial center.
an object of class "timeDate"
.
a length-one object inheriting from class "timeDate"
setting the origin for the julian counter.
a character string denoting the date/time units in which the results are desired.
the time zone or financial center where the data were recorded.
a character string with the location of the financial center named as "continent/city".
currently not used.
arguments passed to other methods.
Generic functions to extract properties of "timeDate"
objects. julian
and months
are generics from base R,
while atoms
is a generic defined in this package.
julian
extracts the number of days since origin
(can be
fractional), see also julian
.
atoms
extracts the calendar atoms from a "timeDate"
object, i.e., the year, month, day, and optionally, hour, minute and
second. The result is a data frame with the financial center in
atrribute "control"
.
months
extracts the months as integers from 1 to 12, unlike
base::months
which returns the names of the months.
