Convert a String column into a Time column
Description
Convert a String column into a Time column
Usage
<Expr>$str$to_time(format = NULL, ..., strict = TRUE, cache = TRUE)
Arguments
format
|
Format to use for conversion. Refer to
the
chrono crate documentation for the full specification. Example:
“%Y-%m-%d %H:%M:%S”. If NULL (default), the
format is inferred from the data. Notice that time zone
%Z is not supported and will just
ignore timezones. Numeric time zones like
%z or
%:z are supported.

If TRUE (default), raise an error if a single string cannot
be parsed. If FALSE, produce a polars null.
|
cache
|
Use a cache of unique, converted dates to apply the datetime conversion. |
Value
