'von gestern sein' (to be outdated) and 'zeitgemäss' are opposites. If something is 'von gestern', it seems old-fashioned or no longer suitable for today's world. 'zeitgemäss', by contrast, means that something fits the present and is modern enough. 'Von gestern' is used more in conversation and is often critical. 'Zeitgemäss' sounds more objective and fits well with rules, technology, teaching, or ways of working.
