database - Should the "last updated" field be initialized to something? -



database - Should the "last updated" field be initialized to something? -

i'm building rest api.

my users have created_at , updated_at fields. these fields hold strings this:

"2014-12-29t12:30:21+0000"

when create user, set created_at current date. however, i'm not sure if should same updated_at. technically, user has never been updated. seems weird there not there.

should leave value null, create same created_at, or else?

creating updating state (from nil something) can safely considered "update".

i set updated time on creation, if no other reason don't have cater null values (ever).

database api rest date timestamp
