convert-tz

Hi I'm so confused with this UTC and GMT I'm inserting in MySQL table as ex column "event_date" like "2010-07-01 23:50:00" (datetime) my client asking an option in front end as GMT +1 GMT +2 GMT -1 GMT -2 ...etc if I select any option GMT +2 the event_date will filter/list according to the GMT +2. I have no idea how to proceed and after googling I found this CONVERT_TZ( `field_eventdate_value` , '+00:00', '+10:00' ) and whether it works well and my client gave me a sample URL to check like this http://www.forexpros.com/economic-calendar/ I'm working with drupal nodes Thanks in advance, Gobi

This sounds simple enough but I haven't been able to figure out how to use a simple SELECT statement to return the current time in GMT. I have been trying to use CONVERT_TZ() to convert NOW() to GMT based on the server time zone and the GMT time zone but for some reason it returns NULL when I put in the text time zones. The only way I get a result is to actually put in the offsets which is getting way too complicated for what should be a really simple operation. Here is what I mean: mysql> SELECT CONVERT_TZ(NOW(),@@global.system_time_zone,'GMT'); NULL mysql> SELECT CONVERT_TZ(NOW(),'PST','GMT'

Can MySQL convert a stored UTC time to local timezon:ed time directly in a normal select statement? Let's say you have some data with a timestamp (UTC). CREATE TABLE `SomeDateTable` ( `id` int(11) NOT NULL auto_increment, `value` float NOT NULL default '0', `date` datetime NOT NULL default '0000-00-00 00:00:00', PRIMARY KEY (`id`) ) Then when I "select value, date from SomeDateTable"; I of course get all the dates as in their stored UTC form. But let's say that I would like to have them in another timezone (with DST), can I then add some magic to the select query so that I get all the dates

I am using this Where Condition in One Of my query with MySql Database.My Problem is that i have one displaytime column in my table but that table column shows the data in UTC Time.and i want to convert that displaytime column in the Local Time Zone.so how can i provide this facility from query itself. I have goggled the things and by that i knew that something like SELECT CONVERT_TZ() will work for that.but its not working for me. Here is my query in which i need to convert displaytime to local time zone...so can anyone please guide me? WHERE displaytime >= '2012-12-01 00:00:00' AND

I know this sounds stupid, but when I use SELECT CONVERT_TZ('2004-01-01 12:00:00','UTC','Asia/Jakarta') AS time it outputs NULL. I'm using MySQL Workbench in Ubuntu 12.04 64 bit, and it works in my other laptop/os (also using MySQL Workbench). This will happen if you haven't loaded the time zone table into mysql. mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql I found this thread after spending some time trying to figure out why after running the command in the accepted answer (which is the same on MySQL's dev site) the command was unable to convert between timezones such as
