everyone
use ISO 8601 or fuck off
thank you
@CobaltVelvet I prefer RFC 3339. 1) The ISO 8601 standard is not freely accessible 2) It is too complicated, with too many variants (unlike what many people say, alphabetic sorting is not time sorting with ISO 8601 in full)

Re: 1) Is http://www.loc.gov/standards/datetime/iso-tc154-wg5_n0039_iso_wd_8601-2_2016-02-16.pdf not good enough? For that matter, ISO language (C/C++ etc.) standards are not "freely accessible" either, though they are essentially interchangeable with their last working drafts, which are. Standards are for implementers anyway, users are normally better off with secondary documentation (e.g. in the case of ISO 8601, Wikipedia).
RFCs are nice though, and 3339 is an ISO 8601 profile as @CobaltVelvet pointed out.
@ntk @CobaltVelvet As you said, it's a draft. And you cannot even redistribute it.
