Since we're still on daylight savings, I'm sure the lounge will be on "summer hours." In any event, if you're just waiting for SQ 015 to depart, you've got nothing to worry about.
If you're flying SQ, then I believe that's true. I've been tossed out while waiting for UA or LH flights. As soon as the passengers for the SQ flight leave the lounge, everyone has to go, regardless of posted hours.
