iso8601

I need to output the current date in the format week-based-year - week-of-week-based-year , i.e. using the ISO week date where the week always starts on a Monday and the first week of the year is the first one that has at least four days in January (so the week with the first Thursday in January). Since 31 December 2015 was a Thursday, the Friday through Sunday, i.e. 1st through 3rd of January 2016, all belong in the 53rd week of 2015 (a "long year"), and the first week of 2016 starts on Monday, 4 January. From the DateTimeFormatter spec , I would have expected that I can just use the pattern

How can I convert duration with JavaScript, for example: PT16H30M crush You could theoretically get an ISO8601 Duration that looks like the following: P1Y4M3W2DT10H31M3.452S I wrote the following regular expression to parse this into groups: (-)?P(?:([.,\d]+)Y)?(?:([.,\d]+)M)?(?:([.,\d]+)W)?(?:([.,\d]+)D)?T(?:([.,\d]+)H)?(?:([.,\d]+)M)?(?:([.,\d]+)S)? It's not pretty, and someone better versed in regular expressions might be able to write a better one. The groups boil down into the following: Sign Years Months Weeks Days Hours Minutes Seconds I wrote the following function to convert it into a

I have a SQLite database where I store the dates as ticks. I am not using the default ISO8601 format. Let's say I have a table defined as follows: CREATE TABLE TestDate (LastModifiedTime DATETIME) Using SQL, I wish to insert the current date and time. If I execute any of the below statements, I end up getting the date and time stored as a string and not in ticks. INSERT INTO TestDate (LastModifiedTime) VALUES(CURRENT_TIMESTAMP) INSERT INTO TestDate (LastModifiedTime) VALUES(DateTime('now')) I have looked at the SQLite documenation , but I do not seem to find any option to obtain the current

how can i sort this array by date (ISO 8601)? var myArray = new Array(); myArray[0] = { name:'oldest', date:'2007-01-17T08:00:00Z' } myArray[1] = { name:'newest', date:'2011-01-28T08:00:00Z' } myArray[2] = { name:'old', date:'2009-11-25T08:00:00Z' } Playground: http://jsfiddle.net/4tUZt/ Thanks in advance! Sort Lexicographically: As @kdbanman points out, ISO8601 See General principles was designed for lexicographical sort. As such the ISO8601 string representation can be sorted like any other string, and this will give the expected order. '2007-01-17T08:00:00Z' < '2008-01-17T08:00:00Z' ===

I'm trying to write a date comparison query using MongoDB's strict JSON representation of BSON . I'd like it to work in the MongoDB shell (v2.4.3) Here's what I've tried... Setup: create a new document with an at date of Jan 1, 2020 > db.myTimes.insert({"at": new Date("2020-01-01")}) Using non-strict query for date > 2010, no problem: > db.myTimes.find({"at": {"$gt": new Date("2010-01-01")}}) { "_id" : ObjectId([snipped]), "at" : ISODate("2020-01-01T00:00:00Z") } Using strict JSON query, however... NO DICE > db.myTimes.find({"at": {"$gt": {"$date":"2010-01-01T00:00:00Z"}}}) > db.myTimes.find({

I'm trying to format a Postgres date representation into a ISO 8601 string. I'm assuming that there is a Postgres function that can do it, but I found the documentation short on examples. My query is SELECT now()::timestamp which returns [{{2016, 8, 9}, {3, 56, 55, 754181}}] I'm trying to get the date into a format that looks more like 2016-8-9T03:56:55+00:00 . What changes do I need to make to my query to make that happen? Thanks for your help. I think I found a way to do the formatting, but it's not ideal because I'm writing the formatting myself. Here is a potential solution: SELECT to_char

This question already has an answer here: Convert timestamps with offset to datetime obj using strptime 4 answers How do I parse an ISO 8601-formatted date? 25 answers So in Python 3, you can generate an ISO 8601 date with .isoformat(), but you can't convert a string created by isoformat() back into a datetime object because Python's own datetime directives don't match properly. That is, %z = 0500 instead of 05:00 (which is produced by .isoformat()). For example: >>> strDate = d.isoformat() >>> strDate '2015-02-04T20:55:08.914461+00:00' >>> objDate = datetime.strptime(strDate,"%Y-%m-%dT%H:%M:

This docs mention moment.ISO_8601 as a formatting option (from 2.7.0 - http://momentjs.com/docs/#/parsing/special-formats/ ), but neither of these work (even 2.7.0): var date = moment(); date.format(moment.ISO_8601); // error moment.format(date, moment.ISO_8601); // error ( http://jsfiddle.net/b3d6uy05/1/ ) How can I get an ISO 8601 from moment.js? cyberwombat moment().toISOString(); // or format() - see below http://momentjs.com/docs/#/displaying/as-iso-string/ Update Based on the answer: by @sennet and the comment by @dvlsg (see Fiddle ) it should be noted that there is a difference between
