The following example modifies the timestamp formatting -to remove the angular brackets during export. It defines a filter function, -makes a filter variable local to the current buffer and adds the new filter -to the filter variable. +You can customize the export for just a specific file by binding export +filter variables using @code{#+BIND}.
