Would like to know which version is proper:
- It's about time you know
- It's about time you knew
Some examples:
- It's about time you know about a cancer diagnosis
- It's about time you knew about a cancer diagnosis
- It's about time you know if you have cancer
- It's about time you knew if you have cancer
- It's about time you know why you're feeling that way
- It's about time you knew why you're feeling that way
- It's about time you know what happened
- It's about time you knew what happened
