Soul/jazz song. Something with 'evening'

Soul/jazz song. Something with 'evening' in the lyric or perhaps "sitting here' 'as the evening goes. A guy whistle in the song. Is more a good mood song. Very famous.

Sittin' in the evening sun
I'll be sitting when the evening comes
watching the ships roll in
and then I'll watch 'em roll away again...
I'm just a'sittin on the dock of the bay
watching the tide roll away
sittin' on the dock of the bay...wasting time......
