Are UtcNow and Now the same datetime? Do they know they're different?

问题 If I run a snippet like: bool areTheyTheSame = DateTime.UtcNow == DateTime.Now what will I get? Does the DateTime returned know its timezone such that I can compare? My specific problem is that I'm trying to build a cache-like API. If it takes a DateTime AbsoluteExpiration, do I have to enforce that users of my API know whether to give me a UTC time or a timezone-based time? [Edit] This SO question is extremely relevant to my issue as well: Cache.Add absolute expiration - UTC based or not?

How is timezone handled in the lifecycle of an ADO.NET + SQL Server DateTime column?

别说谁变了你拦得住时间么 提交于 2020-01-13 11:27:13
问题 Using SQL Server 2008. This is a really junior question and I could really use some elaborate information, but the information on Google seems to dance around the topic quite a bit and it would be nice if there was some detailed elaboration on how this works... Let's say I have a datetime column and in ADO.NET I set it to DateTime.UtcNow. 1) Does SQL Server store DateTime.UtcNow accordingly, or does it offset it again based on the timezone of where the server is installed, and then return it

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

十年热恋 提交于 2020-01-13 02:51:18
问题 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

模块介绍   模块,用一砣代码实现了某个功能的代码集合。   类似于函数式编程和面向过程编程,函数式编程则完成一个功能,其他代码用来调用即可,提供了代码的重用性和代码间的耦合。而对于一个复杂的功能来,可能需要多个函数  才能完成(函数又可以在不同的.py文件中),n个 .py 文件组成的代码集合就称为模块。   如:os 是系统相关的模块;file是文件操作相关的模块   模块分为三种: 自定义模块 内置标准模块(又称标准库) 开源模块   自定义模块 和开源模块的使用参考 http://www.cnblogs.com/wupeiqi/articles/4963027.html time &datetime模块      #_*_coding:utf-8_*_ __author__ = 'Alex Li' import time # print(time.clock()) #返回处理器时间,3.3开始已废弃 , 改成了time.process_time()测量处理器运算时间,不包括sleep时间,不稳定,mac上测不出来 # print(time.altzone) #返回与utc时间的时间差,以秒计算\ # print(time.asctime()) #返回时间格式"Fri Aug 19 11:14:16 2016", # print(time.localtime())

Joda Time: Convert UTC to local

问题 I want to convert a Joda Time UTC DateTime object to local time. Here's a laborious way to do it which seems to work. But there must be a better way. Here's the code (in Scala) without surrounding declarations: val dtUTC = new DateTime("2010-10-28T04:00") println("dtUTC = " + dtUTC) val dtLocal = timestampLocal(dtUTC) println("local = " + dtLocal) def timestampLocal(dtUTC: DateTime): String = { // This is a laborious way to convert from UTC to local. There must be a better way. val instantUTC

How to migrate DateTime values to DateTimeOffset in SQL Server?

拜拜、爱过 提交于 2020-01-11 04:32:10
问题 Given a SQL table with a DateTime column and approx 100k rows of various dates (local time PST values) from the past 3 years, what is the best strategy to migrate those column values to DateTimeOffset to "add" the missing utc tz offset info? The existing DateTime values have been stored without any time zone/utc offset details. The dates stored are always representative of Pacific Time (-800 or -700 depending on Daylight Saving Time). Goal is to retroactively add the tz offset to all existing
