I believe continuous effects would work (e.g. "While this card is on the field, all cards on your field gain +1 critical!"), but not anything that activates during that battle (e.g. "When this card would be attacked, it gains +2000 defense!") as that condition activates during the battle. Not 100% sure though. Also yes you can't activate anything when perpetual time is active, even stuff from hand or drop.
