Hello, I am reading the date man page for the first time and it seems that a `+` must prefix a format string, but this requirement or behavior is not documented.
Example: ```bash date "%H:%M" ---- date: invalid date ‘%H:%M’ ``` ```bash date "+%H:%M" ---- 10:15 ``` The only way I found this is through the default format string on the page linked below. I think this default format string should appear in the man page as well. https://www.gnu.org/software/coreutils/manual/html_node/date-invocation.html#date-invocation MCP
