Title: for (p)expireat use absolute time, without double recomputation

Simplify handling (p)expire(at), now the code (look at offset var) is easier to grasp. Also, now we avoid slight loss of precission in pexpireat (between the call to mstime in expireat command and the one in expiregeneric, the mstime can change). And for (p)expireat, there's no reason to call mstime anyway :-)
