Hi Maarten,
Thanks for your comment - an amateurish oversight of mine - I didn't realise that you had to set the seed for each command - I assumed it was for each session!
Best wishes
Tim

You will get the same dates when you precede the command with the same seed:
set seed 339487731
gen date7 = datediag + ceil(11 * runiform()) - 6
set seed 339487731
gen date8 = datediag + ceil(11 * runiform()) - 6
