Is there a substitute for za'tar?

I have a recipe that calls for the Middle Easter spice za'tar. What can I substitute?

Za'tar is a spice blend that gets a lot of its character from the Middle Eastern spice sumac, which has a mild citrus flavor. To make a spice blend similar to za'tar, combine:

2 teaspoons sumac

1 1/2 teaspoons thyme

1 1/2 teaspoons marjoram

1/4 teaspoon salt

3/4 teaspoon toasted sesame seeds
