Nokia Lumia 720 date time automatic update issue

[TheBedroom]

Hi,

in my new Lumia 720, i set the date+time option to update automatically.
But if i need to do a soft reset (due to phone freeze ), when it restarts the date and time are set to arbitrary value (2012 ??), and even if automatic set is on, it does not update !!!
I think that automatic update does not work at all !!!

how can i solve this problem ?

thank you in advance

made new test: change manually time, (ten minutes ahead right time), then set automatic update again...
now, after 20 minutes this change, time is still wrong... so, the automatic update DOES NOT WORK !!!
