datetime-format

问题 I want to display date in 09/07/2013 format instead of 09-jul-13. Dim dt As Date = Date.Today MsgBox(dt) 回答1: First, uppercase MM are months and lowercase mm are minutes. You have to pass CultureInfo.InvariantCulture to ToString to ensure that / as date separator is used since it would normally be replaced with the current culture's date separator: MsgBox(dt.ToString("dd/MM/yyyy", CultureInfo.InvariantCulture)) Another option is to escape that custom format specifier by embedding the / within

问题 Even though it seems like this question has been asked a bunch of times, I can't seem to find an answer that is specific to my question: I have a variable that is read from an XML file by a C# XML parser. It is a string, and is in the format "yyyy-MM-dd" . I would like to read this variable into our database using SQL , but it needs to be in the proper datetime format in order for me to do this. Unfortunately, I can't find any datetime formats for "yyyy-MM-dd" . Am I missing something? I

问题 I'm trying to understand how to interpret GMT offsets so I can work with datetime objects in R. For example, suppose I have a datetime like "2011-04-04 10:45:00 GMT+10" Q1: Should I read that as a Grenwich time and add 10 hours to get the local time? Or is it a local time and I need to subtract 10 hours to get GMT? I always understood it was the latter. Q2: Why does R seem to use the former interpretation? For example foo <- as.POSIXct("2011-04-04 10:45:00", tz="Etc/GMT+10") attr(foo, "tzone"

问题 I have a Webapp using Angular v4.0.1 and ngx-charts (uses d3) v5.1.2 creating a line-chart where the x-axis has date-values. My Problem is that the x-axis does not show the german time-format.

问题 If I have a bunch of data with date & time in UTC format , how can I convert them to EST . It can determine when they will be -4(in summer) and - 5(in winter) automatically every year? Thanks 回答1: You'll need to use the pytz module (available from PyPI): import pytz from datetime import datetime est = pytz.timezone('US/Eastern') utc = pytz.utc fmt = '%Y-%m-%d %H:%M:%S %Z%z' winter = datetime(2016, 1, 24, 18, 0, 0, tzinfo=utc) summer = datetime(2016, 7, 24, 18, 0, 0, tzinfo=utc) print winter

问题 I am having trouble deserializing a org.joda.time.DateTime field from JSON into a case class. The JSON: val ajson=parse(""" { "creationDate": "2013-01-02T10:48:41.000-05:00" }""") I also set these serialization options: implicit val formats = Serialization.formats(NoTypeHints) ++ net.liftweb.json.ext.JodaTimeSerializers.all And the deserialization: val val1=ajson.extract[Post] where Post is: case class Post( creationDate : DateTime){ ... } The exception I get is: net.liftweb.json

问题 I have the following code in C#: DateTime dt = GetDateTime(); string formatted = dt.ToString("yyyyMMddTHHmmsszz"); which returns a date in the following format: 20100806T112917+01 I would like to be able to get the same results in VBScript (for a legacy ASP application).
