I sent an email to the guy on the WG 14 contact section but I didn’t expect to get an answer anytime soon, however, I did. This is what he replied to me: the Committee has not discussed starting work on a new revision of the Standard. WG 14 will be meeting in Parma Italy … Read more
Welcome to Python datetime! Dealing with dates and times is necessarily complex, and Python doesn’t come fully with batteries included in this case. You can’t use %z in strptime because Python has no classes to represent timezones (you are supposed to implement your own, or better yet include some other libraries). You want to use … Read more
The most recent example I can find is the UNISYS 2200 series, based on UNIVAC, with ones-complement arithmetic. The various models were produced between 1986 and 1997 but the OS was still in active development as late as 2015. They also had a C compiler, as seen here. It seems likely that they may still … Read more
There is an ISO standard for Country code, but none (that I can find) for city code. There is, however; a United Nations Economic Commission for Europe United Nations Code for Trade and Transport Locations system of city identification UN/LOCODE. Edit: Lined out the wrong name, added the slash to the UN/LOCODE name.
For what it’s worth, Herb Sutter wrote an article touching on this issue, and there’s a fair bit of discussion in the comments: http://herbsutter.com/2010/03/03/where-can-you-get-the-iso-c-standard-and-what-does-open-standard-mean/ As he mentions, “open” does not necessarily mean “no-cost”. As far as students or others with limited financial means who might want free versions of thee documents, note that: many references … Read more
Try the following format: %Y-%m-%dT%H:%M:%S.%fZ For example: >>> datetime.datetime.strptime(‘2012-05-29T19:30:03.283Z’, ‘%Y-%m-%dT%H:%M:%S.%fZ’) datetime.datetime(2012, 5, 29, 19, 30, 3, 283000) The Z in the date just means that it should be interpreted as a UTC time, so ignoring it won’t cause any loss of information. You can find this information here: http://www.w3.org/TR/NOTE-datetime
Here’s the specification of the ISO base format, and here is the MP4 file format specification, both defined as part of the ISO/IEC 14496 standard. Also take a look at the QuickTime MP4 specification. It has a very clear explanation.
With the isoweek module you can do it with: from isoweek import Week d = Week(2011, 40).monday()
The RegionInfo class does know the three-letter code (in the ThreeLetterISORegionName property), but I don’t think there is a way to get RegionInfo based on this code, you would need to enumerate all regions and add them to your own dictionary, with the three-letter code as a key. However, I think the .NET Framework uses … Read more
It’s required unless the “partners in information interchange” agree to omit it. Quoting an earlier version of the ISO 8601 standard, section 4.3.2: The character [T] shall be used as time designator to indicate the start of the representation of the time of day component in these expressions. […] NOTE By mutual agreement of the … Read more
