DateTime _is_ quite heavyweight, but it's also generally right, and there's a whole suite of modules which work with it, meaning that you can live almost entirely in the DateTime world for all your date- and time- stuff. For any one individual task you can likely come up with a module which just does that and does it more leanly, but there is an advantage in having various date- and time-based modules working together, and also in having them being based on something which gets right all the really awkward bits (such as leap seconds, time zones, and daylight-saving time); even if you don't need that, somebody else will. It's a bit of a chicken-and-egg thing, but obviously DateTime is only an awkward prerequisite of a module if you don't already have it installed. And the more people who embrace DateTime, the more it will be seen as a reasonable module for othewr things to be based on. > ... and seems to be able to parse, but not format. I haven't looked at DateTime::Format::ISO8601, but if that is the case then I suspect it's because DateTime emits in ISO 8601 format by default, so you don't need to do anything special to get it.
