It has values like London, Casablanca, Arizona, Pacific Time (US & Canada) etc. Based on the time_zone , I want to get the DateTime result of that time zone. For example, Current time = 8/3/2015 4:00:00 PM If time_zone = Central Time (US & Canada) then result should be 8/3/2015 3:00:00 PM, If time_zone = Pacific Time (US & Canada) then result should be 8/3/2015 1:00:00 PM, If time_zone = London then result should be 8/3/2015 9:00:00 PM and so on. I want to display the current time as well as

Why is this giving me 2 different sets of timezones?

So how could I get around this issue. Like I want to deal in UTC but I want to have the default selected item to be "Coordinated Universal Time" what is not in the gmt list but in the UTC list. So I am not sure what to do. (I am not a shared host so if you can change it on windows 2008 machine it won't help me much). Hi I have this line to get all the timezones Dictionary<string, TimeZoneInfo> storeZoneName =

sas datetime to R date format

I have ported this dataset into R using the sas7bdat package but the datetime variable is shown in integer number format (e.g. 1706835972). Is there any way to convert this integer into a date format? 回答1: To match exactly what SAS outputs for default datetime structure, you need to use as.POSIXct as was mentioned in comments, and additionally use the tz=UTC argument: sasDateTimes <- c(1706835972, 1716835972, 1726835972, 1736835972, 1746835972, 1756835972, 1766835972, 1776835972,

How to get the real UTC timestamp (client independent)?

I know with JavaScript's getTime() I can get the UTC timestamp in milliseconds. It's independent of the client's timezone, but I think it's dependent of the client's current time. I'm trying to make a live clock that shows the real UTC time, so it shouldn't matter if the client's time is set correctly or not for it to be correct. 回答1: Get this JSON: http://json-time.appspot.com/time.json Or http:

互联网渗透测试之Wireshark的高级应用 1.1说明 Wireshark的一些高级特性 TCP协议,想要查看Tcp流中的应用层数据,"Following TCP streams"功能将会很有用。如果你项查看telnet流中的密码,或者你想尝试弄明白一个数据流。或者你仅仅只需要一个显示过滤来显示某个TCP流的包。这些都可以通过Wireshark的"Following TCP streams"功能来实现。 TCP包,然后选择Wireshark工具栏菜单的"Following TCP Streams"选项(或者使用包列表鼠标右键的上下文菜单)。然后,Wireshark就会创建合适的显示过滤器,并弹出一个对话框显示TCP流的所有数据。如所示 注意 值得注意的是:Follow Tcp Stream会装入一个显示过滤来选择你已经选择的Tcp流的所有包。 图 A到B的通信标记为红色,从B到A的通信标记为蓝色。当然,如果你喜欢的话你可以从"Edit/Preferences"菜单项的"Colores"修改颜色。 XXX - What about line wrapping (maximum line length) and CRNL conversions? TCP流不能实时更新。想得到最近的内容需要重新打开对话框。 你可以在此对话框执行如下操作: Save As 以当前选择格式保存流数据。

GMT、UTC、UNIX时间戳、时区

UTC时间:世界协调时间(UTC)是世界上不同国家用来调节时钟和时间的主要时间标准,也就是零时区的时间。UTC是以原子时秒长为基础,在时刻上尽量接近于GMT的一种时间计量系统。为确保UTC与GMT相差不会超过0.9秒,在有需要的情况下会在UTC内加上正或负闰秒。UTC现在作为世界标准时间使用。 GMT:即格林尼治标准时间,也就是世界时。GMT的正午是指当太阳横穿格林尼治子午线(本初子午线)时的时间。但由于地球自转不均匀不规则,导致GMT不精确,现在已经不再作为世界标准时间使用。所以,UTC与GMT基本上等同,误差不超过0.9秒。 CST时间:中央标准时间 如:当UTC时间为0点时,中国CST时间为8点,因为零时区和中国北京时区相差8个时区。 地球自西向东旋转,东边比西边先看到太阳,东边的时间也比西边的早。为了统一世界的时间,1884年的国际经度会议规规定将全球划分为24个时区(东、西各12个时区)。规定英国(格林尼治天文台旧址)为零时区(GMT+00),东1-12区,西1-12区,中国北京处于东8区(GMT+08)。 若英国时间为6点整,则GMT时间为6点整,则北京时间为14点整。 计算机中的UNIX时间戳,是以GMT/UTC时间「1970-01-01T00:00:00」为起点,到具体时间的秒数,不考虑闰秒。这么做当然是为了简化计算机对时间操作的复杂度。

使用Python将字符串转换为格式化的日期时间字符串

我正在尝试将字符串“20091229050936”转换为“2009年12月29日(UTC)” >>>import time >>>s = time.strptime("20091229050936", "%Y%m%d%H%M%S") >>>print s.strftime('%H:%M %d %B %Y (UTC)') 给 AttributeError: 'time.struct_time' object has no attribute 'strftime' 显然,我犯了一个错误:时间错了,它是一个日期时间对象! 它有一个日期 和 时间组件! >>>import datetime >>>s = datetime.strptime("20091229050936", "%Y%m%d%H%M%S") 给 AttributeError: 'module' object has no attribute 'strptime' 我是怎么意思将字符串转换为格式化的日期字符串? 解决方案 time.strptime 返回 time_struct ; time.strftime 接受a time_struct 作为可选参数: >>>s = time.strptime(page.editTime(), "%Y%m%d%H%M%S") >>>print time.strftime('%H:%M %d

ARM Linux RTC 时间的读取与设置

匿名 (未验证) 提交于 2019-12-02 21:59:42
  RTC 芯片采用 PCF8563T,Linux 系统使用 date 设置时间后用 hwclock -w 同步到 RTC,一段时间后 Linux 系统时间与本地时间相差 8 个小时。   直觉告诉我们这是时区造成的,要么是系统的时区配置不对,要么是 RTC 时间的读写不对。 时区配置主要是两个文件:/etc/localtime 和 /etc/timezone,内容如下,看来是已经配置成 CST(中国标准时间)的了。 # ls -l /etc/localtime lrwxrwxrwx 1 root root 33 Jan 1 1970 /etc/localtime -> /usr/share /zoneinfo/ Asia / Shanghai # cat /etc/timezone Asia/Shanghai 设定了时区,还要确定 Linux 系统的时间方案。Linux 支持 UTC 时间,也就是本初子午线上的时间,它和以前的格林尼治时间(GMT)的区别似乎在于 UTC 是由多个原子钟平均出来的。 协调世界时,又称世界统一时间、世界标准时间、国际协调时间。由于英文(CUT,Coordinated Universal Time)和法文(TUC)的缩写不同,作为妥协,后来都统一简称 UTC。   在文件 /etc/default/rcS 中,设定了系统是否使用 UTC,UTC=yes

Mysql: Convert DB from local time to UTC

落爺英雄遲暮 提交于 2019-12-02 17:42:29
I need to convert an existing (datetime fields) db from local time ut UTC. The values are stored ad datetimes on a server with time zone CET (+1) (with summertime +2). When selecting data I use UNIX_TIMESTAMP() , which magically compensates for everything, ie, time zone shift and dst (if i've read the docs right). I'm moving the db to a new server with UTC as system time. Simply subtracting -1 H won't work, as summer time is +2. Any ideas for a clever way to do this? (using sql or some script lang) First you need to make sure the mysql.time_zone_name table is populated. If it's empty, you can
