gio:file-info-creation-date-time (info)

info -- a g:file-info instance
time -- an unsigned integer for the Lisp universal time

Gets or sets the creation time of the current info. It is an error to call this if the info does not contain the "time::created" attribute. If the "time::created-usec" attribute is provided, the resulting universal time will additionally have microsecond precision.

If nanosecond precision is needed, the "time::created-nsec" attribute must be queried separately using the g:file-info-attribute function.
