Если речь о сослагательном наклонении в конструкции it is (about) time someone did something, то правильно так:
He looked at his watch and decided it was time he made another call.
Он посмотрел на часы и решил, что пора бы ему позвонить снова.
Несмотря на то, что сказуемое looked стоит в форме Past Simple, сказуемое в придаточном he made another call стоит в форме made (а не had made). Причина в том, что в данной конструкции не соблюдается согласование времен.
he looked at his watch and decided it was time to make another call
He looked at his watch and decided it was the time to make another call.
