Usage

<Expr>$str$to_time(format = NULL, ..., strict = TRUE, cache = TRUE)

Arguments

Notice that time zone %Z is not supported and will just ignore timezones. Numeric time zones like %z or %:z are supported.
…	Not used.
strict	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.
