Comma after introductory clause/phrase

Hi,

I am confused whether a comma is required after "since" in the following sentence:

Since 1945 there has been no decade with as many financial crises as the 1990s.


Similarly, is a comma required in the following sentence after 1997:

In 1997 Asia was fit by a financial crisis.


I have a feeling that it is required in the first case but not in the second.

If you have a specific question, I suggest you start a new thread, rather than adding on to an old one, and be more specific about what you need help with.
