utc

How can I convert the time zone of a date string in php without changing the default time zone. I want to convert it locally to display only. The php time zone settting should not be modified. EDIT: My source time is a UTC string, I want to convert it to a different format, retaining the time zone as UTC, but php is converting it to local timezone. The code I used was: date('Y-m-d H:i::s',strtotime($time_str)); How do I retain timezone? $src_tz = new DateTimeZone('America/Chicago'); $dest_tz = new DateTimeZone('America/New_York'); $dt = new DateTime("2000-01-01 12:00:00", $src_tz); $dt-

I would like to save a timestamp to the database without being converted to the local timezone by the jdbc driver. Currently only MySQL and PostgreSQL are important for me but i would appreciate if there is a database independent solution. Example: // i want that to be saved as 1970-01-01 00:00:00 TimeStamp ts = new java.sql.Timestamp(0); // gets transformed to local time by jdbc driver (in my case to 1970-01-01 01:00:00) st.setTimestamp(0, new java.sql.Timestamp(0)); // only works using postgres (mysql connector seems to ignore the calendar) // postgres => 1970-01-01 00:00:00 // mysql => 1970

CentOS7提供三个命令行工具，可用于配置和显示有关系统日期和时间的信息。 timedatectl： Linux 7中的新增功能，也是systemd其中的一部分。 date：系统时钟，也成为软件时钟，一旦系统启动并且系统时钟被初始化，系统时钟就完全独立硬件时钟。 hwclock： real-time clock ( RTC )通常被称为 硬件时钟 ，（在系统集成电路板上）,即使在机器关闭时也能正常工作。实时时钟可以使用UTC（ Universal Time ）或本地时间，建议使用UTC。 使用 timedatectl 命令 显示当前日期和时间： 1 timedatectl 1 2 3 4 5 6 7 8 9 [root@zydev ~] # timedatectl Local time : Mon 2017-11-06 01:22:46 CST #中部标准时间，UTC+8 Universal time : Sun 2017-11-05 17:22:46 UTC RTC time : Sun 2017-11-05 17:22:46 Time zone: Asia /Shanghai (CST, +0800) NTP enabled: no NTP synchronized: no RTC in local TZ: no DST active: n /a

I have a few columns in an SQL server 2008 R2 database that i need to convert from local time (the time zone the sql server is in) to UTC. I have seen quite a few similar questions on StackOverflow, but the answers all fail to work correctly with daylight saving time, they only take into account the current difference and offset the date. I could not find any way at all doing this using T-SQL alone. I solved it using SQL CLR: public static class DateTimeFunctions { [SqlFunction(IsDeterministic = true, IsPrecise = true)] public static DateTime? ToLocalTime(DateTime? dateTime) { if (dateTime ==

?useUnicode=true&characterEncoding=UTF-8&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC 　　 idea编辑器是一个非常常用的软件，它不仅可以编写代码还是给数据库作为图形界面。别的数据不说，就mysql而言吧。你如果直接配置的话。 比如： 光是这样配置是不行的，就会出现如下的错误。 这时数据库是没有显示数据的，右下角也有报错信息。 说到这里你就会知道你的数据库在idea这里配置有问题了。那么你试试以下的两种方法，可以很好的解决这个问题 第一： 　　 这Database这里添加一点配置： ?useUnicode=true&characterEncoding=UTF-8&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC 　　加上就没问题了 还有第二种就是： 点击箭头所指的地方，然后在这边找一个serverTimezone 把它的值改为UTC 效果如下： 　　 这样就可以在idea使用mysql数据库了。 如果本文章对你有所帮助，请帮我点个赞哦！！ 来源： https://www.cnblogs.com

I've been looking around for a few hours now about what's the best way to use timezones in a PHP/MySQL web application, finding a definitive answer is hard. From what I've learnt so far it is best to store everyones stuff in the database in UTC (correct me if I am wrong). When a user registers I will ask them for there timezone and then store that against there user. This would be in this format as a dropdown menu: <option value="Europe/London">(GMT) Greenwich Mean Time : London</option> The app I am building will allow users to set arrangements in the future with people (meetings), much like
