问题 I have a DateTime varchar in this format: 2005-08-08T00:00:00+01:00. Does this format have a name? (it's not ISO8601. Is it RFC3339?) How can I convert it to a DateTime using Transact-Sql? EDIT Here's a summary answer, cobbled together from others input: It is ISO8601 with a time offset from UTC. If it was UTC it would end with a 'Z' instead of '+01:00'. wikipedia You can convert it to local time or to utc as follows: DECLARE @d VARCHAR(25) SET @d = '2007-08-08T00:01:00+01:00' SET @d = '2007

问题 My JSF pages display DateTime from managed beans in this format: "MM/dd/yyyy h:mm a" I want avoid duplicate converter declaration in different pages: <f:convertDateTime type="both" pattern="MM/dd/yyyy h:mm a" dateStyle="short" timeStyle="medium" /> Is there a way to make the above converter default for all DateTime fields? (Experience with JSF 2: 2 months.) 回答1: Just extend the DateTimeConverter class behind <f:convertDateTime> and set the defaults in the constructor. @FacesConverter(

问题 I have date time below conversion logic in Javascript which is converting the UTC time into passed timezone's local time. I am wondering this logic will work fine during Daylight transition? If not what is the remedy for that? I can't use any third party library. I have to use pure javascript or Angular JS. function myTime() { var d1= document.getElementById("txtDate").value; var zOffset = document.getElementById("txtOffset").value; console.log("Date1",d1); var d2 = new Date(d1.replace(/ /g,

问题 I'm wondering regarding the output of the following example: when parsing 01/03 , will it be resolved as Mar, 1st or Jan, 3rd ? 回答1: Ruby is not locale dependent. Because Ruby is a server-side language and not a client-side language like JavaScript, Ruby uses the system clock from your web app server - and uses this information to calculate the time. Whatever timezone you have your system set to is what your Ruby app will use. When parsing a date from a string, DateTime will make its best
