Everyone can timestamp everything at any time; the time-proof is valid regardless of who initiates its creation.
For example, at 01:37 on okt 12, I signed this kind 1040 event:
Which contains a proof that this kind 1 event can be tied into bitcoin block 865239:
And the timestamp of block 865239, is 00:02 on okt 12.
The event itself claims it was signed 22:11 on oct 11; this may be a lie still, but at least it was not signed much more than 1 hours and 51 minutes later.
Aside from all these time related dates, the described lunch date could also just be a complete fabrication of course; at the very least the pictures correspond with the stated dishes
