A timestamp and a timestamp with time zone are two different things and you need to use the appropriate one (which is usually time zone with timestamp). However, the argument is really not about attaching timezone information to timestamp which is an unfortunate but necessary thing, but storing times in the archaic multiple-base mixed format stuff humans traditionally use (because it's human-friendly) that computers simply do not need. An ISO timestamp mixes bases 60, 24, 12, a weird mix of base 28, 29, 30 an 31, and a weird mix of 365 & 366. This is craziness.
