In legatura cu formatul din dreptul lastmod, pare a fi corect:

Your Sitemap contains one or more invalid dates. This could be because a date is in the incorrect format, or the date itself is not valid. Dates must use W3C Datetime encoding, although you can omit the time portion. For instance, the following are both valid:

2005-02-21
2005-02-21T18:00:15+00:00
Dates that are in the correct format may be invalid if they specify a time but no timezone. Dates that specify no time are valid (the time defaults to 00:00:00Z).
