+* The **%d**, **%sd** and **%bd** patterns use the date and time from the PCB and schematic. When abscent they use the file timestamp. The `date_time_format` global option controls the format used.
+* The **%D** format is controlled by the `date_format` global option.

+In all cases the format is the one used by the `strftime` POSIX function, for more information visit this [site](https://strftime.org/).

 #### Filtering KiBot warnings
 
 KiBot warnings are marked with `(Wn)` where *n* is the warning id.
