How to convert a date to UTC properly and then convert it back?

孤街浪徒 提交于 2019-12-04 18:07:50
问题 I'm struggling with converting DateTime to UTC, the concept and all, something I'm not understanding correctly. When I get a date time string, say "7/10/2013", I simply do Convert.ToDateTime("7/10/2013").ToUniversalTime(); This will record it as "7/10/2013 4:00:00 AM " in the database. Server is located at U.S East Coast (-5). Of course, during July 2013, DST is still being observed, so offset during that time is -4, such the extra 4 hours 4:00:00 AM " recorded as UTC. As I'm writing this

With the Win 10 Oct 2018 update, Windows is leap second aware. Is .NET's DateTime, too, now?

元气小坏坏 提交于 2019-12-04 17:00:25
In 2012, there was a question here on SO, whether .NET's DateTime are capable of recognizing leap seconds. [1] The answer was no. The documentation is still explicitly stating that it is not. [2] However, Windows Server 2019 and the Windows 10 October 2018 update made Windows itself leap second aware. [3] This begs the question: is .NET inherently leap second aware now? More specifically: can I make my DateTime structures leap second aware as well, by somehow opting in? Edit: From a MS Word document titled "Quest: Write a Leap Second Aware Application on Windows" [4] (emphasis by me): Known

Parsing ISO8601 date/time with DateTime struct

怎甘沉沦 提交于 2019-12-04 16:59:30
I am trying to parse an ISO8601 formatted date/time string with .NET's DateTime structure. In order for me to give a full underdstanding of the problem, I am going to perform tests using both .NET and JavaScript. I am currently in Britain (British Summer Time, which is UTC+01:00). My understanding of ISO8601 is that: When the string is suffixed with "Z", the time is expressed in UTC. When the string is suffixed with "+/-hh:mm", the time is expressed in Local time, where the "+/-hh:mm" expresses the offset from UTC. Consider the following ISO8601 date/time format string: "1987-01-05T08:45:30


k8s与CICD--利用flux部署应用到kubernetes

风流意气都作罢 提交于 2019-12-04 16:37:44
前言 一直在思考部署应用到k8s的姿势,之前介绍过helm,个人感觉helm把记 录数据放到k8s中不是特别好。最近发现了weave的 flux 项目(A tool for deploying container images to Kubernetes services)。 flux简介和注意事项 flux简介 先上图,大致看一下flux的理念。 1:flux可以和任意你喜欢的CI工具搭配比如:Drone,CircleCI,gitlabCI等。实际上flux做了CD的环节。 2:flux可以帮助你安全地更新应用。一般会遇到更新过程出错的问题,在flux实现中, 每个部署的应用的yaml文件存储在git仓库里 ,所以每次更改都可以追踪,所以也能精确回滚到任何一个历史版本。这点我是觉得非常好的。当应用需要更新镜像的时候,有以下几个步骤: Clone the repository Find the deployment files that use the image in question (there may be more than one, since we have e.g., sidecar containers that use the same image) Update a few fields in each file, in slightly different

How to get UTC time with windows batch file

末鹿安然 提交于 2019-12-04 16:07:55
I have been trying to find a way of getting a windows batch file to display the current UTC time when run. So in other words get the current amount of milliseconds since it was initiated in 1970. Does anyone know how to do this. Using WMI: for /f %%x in ('wmic path win32_utctime get /format:list ^| findstr "="') do set %%x This will set the variables Day , DayofWeek , Hour , Minute , Month , Quarter , Second , WeekInMonth and Year which you can use, then. You won't get a time with Unix epoch from Windows easily, though. If you have PowerShell you can use [long]((date).touniversaltime()-

They all come back on my debug sampler as.. myNewDate=Invalid Date dt1=Invalid Date vars.put("myendDate", vars.get("endDate")); var dt = new

Django DateTime field to generate timestamp fields withOUT timezone

纵然是瞬间 提交于 2019-12-04 14:52:43
I am working on a Django application where I need all the postgres represented datetime fields to be saved in UTC (as they should). When I'm creating models with DateTime fields they database representation is generated as " timestamp with time zone ". Although I can manually alter the tables to remove the timezone from the fields, I was wondering if the DateTime model field has the ability to not do that - i.e., create " timestamp with out time zone " for some fields. Is that possible? Or do I have to alter them tables? Thanks, Harel The data types for postgres in Django map to the string

Display local time from utc time stored in sql database on asp.net app

…衆ロ難τιáo~ 提交于 2019-12-04 08:15:37
I've got times saved in a sql database in utc format. I'm displaying those times on a gridview, however they are still UTC format. I'd like to convert them to the client's browsers local time. The problem is that although I can get the timezone offset that is only for the current date/time. That offset could change if some of those dates in the future end up occuring during daylight savings time. I'm relatively new to web programming but it seems like what I need to do is run some Javascript as each entry binds to the gridview that somehow takes the C# datetimeoffset object and converts it to
