I have a SharePoint 2013 On-Premises farm, and the regional settings are set to 'Ireland' (for which date format is dd/mm/yyyy). If I create a Blog Post in my personal site on 6th Jan 2014, it shows up under the Blog post Title as 1st June 2014, even though in the Posts library I can see it thinks correctly that the post was modified on 6th Jan.
If I create a post on 19th June, it will not show the date at all (19/06/2014). Somewhere between the storing and the displaying of the date it seems to be assuming a US Date (mm/dd/yyyy), and being confused when it gets a date that is obviously not a correct US Date.
Interestingly this only seems to happen on users MySite Blogs (which have not been customised at all), and not on a Blog site set up on the Intranet.
Does anybody know what is going on and what could be done to resolve this?
