Francesco,

from my experience I suggest you to speak with Siemens in Milano, the rest is a sparse bunch of "niubbi".

I have got similar problems (not so great) with time sync of S71200 so I avoided it because my machine was depending on clock so I wasn't able to tolerate a fault in synchinc the clock.

If it can work for you and if you like it you can (I repeat this is a work around):

Leave the TIME and DATE in plc and in HMI you just visualize it.

If you want to change the time or date you can do that easily from HMI that sends the new date and time to PLC.

PLC is able to handle flawlessly the GMTs and the daylight times...

Finally solved, for the moment! 

I had to change the CPU, tomorrow I will look for some way to completly reset the old one: it looks like if there is a "BIG BUG" in TIA with this CPU, the function "time syncronization" on DP as master has generated this "RT shutdown" only with the project done with TIA (as told you, with winccflex2008 was working, but re-do everything is a big job).

As Ayman told me, this CPU is not released for TIA, but it still in the catalog, so you can use it at your risk, now all we know how big is this risk! 

I'm unbelievable that Siemens can allow this...

The italian support, once again (I've asked only two times in true), was useless, from the beginnig they just asked me "why don't you migrate your project from V11 to V13???"  

Really thank you to all for the support, if you know the best way to complete reset that CPU let me know: a complete download it's not enought to solve the problem...

Kind regards,

 the target is syncronize the plant, but I've done something similar: just took the time written in a DB from outside and reported on the RT (the CPU will stay with the wrong clock, maybe, since I don't need to schedule anything).

Thank you, kind regards,

 Oh ok , great and simple idea... Just keep in mind that if CPU stays in a bad date/time if you (one day) need to check the alarm history you will have strange days references, of course.

I work near Milano too and never had problems with Siemens of Milan. But of course if they fail the last change is germany (product support?) after that religion...
