http://d.puremagic.com/issues/show_bug.cgi?id=8646 Summary: std.datetime ISO strings are incompatible with ISO 8601 Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: normal Priority: P2 Component: Phobos AssignedTo: nobody@puremagic.com ReportedBy: jens.k.mueller@gmx.de --- Comment #0 from jens.k.mueller@gmx.de 2012-09-12 10:03:23 PDT --- According to http://en.wikipedia.org/wiki/ISO_8601 ISO 8601 date time strings contain nothing below seconds. But the std.datetime's ISO function contain values for this. Hence, it is currently incompatible with ISO 8601. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |

Reread the Times section. You can have "decimal fractions" (which is a really screwed up term IMHO, since decimals and fractions are different things, but whatever) to any of the three time elements - including seconds. The number of decimal places to use "needs to be agreed to by the communicating parties," but the notation is correct. If there's a problem, it's the fact that fromISOExtString doesn't accept variants of ISO-8601 that toISOExtString doesn't use (e.g. using a comma instead of a decimal or having decimal fractions for minutes). But they both follow the standard. There are other places online that fractional seconds are discussed as well. e.g. http://www.cl.cam.ac.uk/~mgk25/iso-time.html -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |

I see now that the standard allows for fractional seconds. In my use case I'm programming against against a specification that demands ISO 8601 conformity without fractional seconds. Is there an easy way to remove the fractional seconds? Because if there are no then toISOExtString() won't return them. My current workaround is quite tedious for this common operation. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |

So, something like sysTime.fracSec = FracSec.from!"msecs"(0); (I should probably add a static property to FracSec which gives you 0, but there isn't anything like that right now). Then when you call toISOString or toISOExtString, it doesn't have any fractional seconds, so the resultant string won't have them. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
