Calculating expiry date of a product

[tsenghiuman]

Hey guys, i am writing to post a question:

i need to manually input the startdate, and i have a value of hours to expire (i.e. in 48 hours),
for example,
06 Feb 2017 09:00 is the startdate, and the expiryhours is 48 hours
The the expirydate should show '08 Feb 2017 09:00'
i have tried sth like expirydate=startdate+(Expiryhours/24)
but it can't work, can anyone would help me?? thanks very much!!!!!!!!!!!!!!!!!!!!!!!!

Thanks for the reply, but i still can't get what i want
maybe due to the date i formatted is ("dd mmm yyyy")
