Is EST5EDT equal to ET?

由 天大地大妈咪最大 提交于 2020-08-11 03:55:09
问题 I know that ET (Eastern Time) has the DST from EST and EDT, but im looking for that timezone in different libraries of different programming languages and ET is not an option, but EST5EDT is. Thanks. 回答1: Short answer : No, They are not equal because EST5EDT doesn't have any history of changes that US Eastern Time has been through. Use America/New_York instead, which does. Longer answer: EST5EDT is a POSIX time zone definition which can be used in a TZ environment variable on many systems.

通过Python扫描代码关键字并进行预警

近期线上出现一个bug，研发的小伙伴把测试环境的地址写死到代码中，在上线前忘记修改，导致线上发布的代码中使用了测试环境地址。 开发过程中虽然有各种规范制度，但是难免有粗心，与其责备不如通过技术手段将问题进行避免。 为了达到上述需求，初步想通过以下步骤来实现代码关键字自动扫描告警。 Python安装 Git安装 GitPython安装 定时任务配置（方案一：crontab 方案二：APScheduler） git代码获取 关键词扫描 邮件告警 #安装python的依赖包 yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz- devel libffi-devel gcc #下载Python安装包，版本号：Python-3.7.1.tgz（在/ opt下创建目录Python3） wget https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tgz #解压安装包 tar -zxvf Python-3.8.1.tgz #指定python3安装目录 ./configure --prefix=/usr/local

Checking if date is in UTC format

由 眉间皱痕 提交于 2020-07-06 23:25:52
问题 Im using the pytz module to translate a date in America/Los_Angeles timezone to utc by the code below : TZ = 'America/Los_Angeles' from = pytz.timezone(TZ) utc = from.localize(original_date).astimezone(pytz.utc) Now,i want to test if utc value is actually in UTC format or not. How to do that with pytz or datetime ? Please Help Thank You 回答1: utc.tzinfo == pytz.utc # returns True if utc in UTC Example: now = datetime.datetime.now(pytz.utc) now.tzinfo == pytz.utc # returns True now = now

Arrow-一个最好用的日期时间Python处理库

转自：https://www.jianshu.com/p/c878bb1c48c1 写过Python程序的人大都知道，Python日期和时间的处理非常繁琐和麻烦，主要有以下几个问题： 有众多的package，类和方法，包括time，datetime，pytz等等 经常需要各种转换，比如时间戳，structtime，时间字符串之间相互转换，localtime和utctime的转换 难以记忆，有违人性的时间格式化字符串%Y %M %m %D %d 基于以上几点，每次做时间处理的时候总是需要翻看以前的代码或者文档，可见此处Python做的有多烂，好了废话不多说，今天给大家介绍的这个arrow极大地解放了我等Python程序员的脑容量。 安装 pip install arrow 使用 获取当前时间 In [13]: import arrow In [14]: t = arrow.utcnow() In [15]: t Out[15]: < Arrow [ 2017-02-01T08:30:37.627622+ 00:00]> In [19]: arrow.now() Out[19]: < Arrow [ 2017-02-01T16:32:02.857411+ 08:00]> 通过utcnow()和now()分别获取了utc时间和local时间，最终获取的是一个Arrow时间对象

Python pytz timezone function returns a timezone that is off by 9 minutes

问题 For some reason which I haven't been able to figure out yet, from the the following code: >>> from pytz import timezone >>> timezone('America/Chicago') I get: <DstTzInfo 'America/Chicago' LMT-1 day, 18:09:00 STD> When, I assume, I should get: <DstTzInfo 'America/Chicago' LMT-1 day, 18:00:00 STD> ...since I don't think that my timezone is 6 hours and 9 minutes away from UTC. I have looked at the source code for pytz but I will admit that I haven't exactly been able to figure out what is going
