bdTimeDate
object from a character vector, a vector of julian days, or a vector of milliseconds, or construct an empty
bdTimeDate
object.
This function requires the bigdata library section to be loaded.

bdTimeDate
object derived from the inputs.
If
charvec
is given, values are read from
its character strings using the format string from
options("time.in.format")
.
If
charvec
is not supplied, then
julian
and/or
ms
are used to construct the bdTimeDate vector.
