getModificationDateTime
Gets the modification time of the current @info and returns it as a #GDateTime.
It is an error to call this if the #GFileInfo does not contain %G_FILE_ATTRIBUTE_TIME_MODIFIED. If %G_FILE_ATTRIBUTE_TIME_MODIFIED_USEC is provided, the resulting #GDateTime will additionally have microsecond precision.
If nanosecond precision is needed, %G_FILE_ATTRIBUTE_TIME_MODIFIED_NSEC must be queried separately using g_file_info_get_attribute_uint32().
Return
modification time, or null if unknown
