Yes.

The sin bin clock starts the moment the player crosses the sideline. It keeps running and only stops if the referee calls time off or blows the whistle for half-time.

In your example, the player is binned at 38 min and then the half runs to 42 min, the player will be allowed to return at the first break in play (scrum, line-out, penalty or free-kick) after the sixth minute of the second half.
