Last modification
[optional] 		The date of last modification of the file.
This date should be in W3C Datetime format.
This format allows you to omit the time portion, if desired, and use YYYY-MM-DD.

Note that this tag is separate from the If-Modified-Since (304) header the server can return, and search engines may use the information from both sources differently.
