Note, the time zone info takes up about 5 MB in MySQL. Then, to view a list of time zones, just do the following: USE mysql You could also just add it to a weekly or monthly cron job to do it for you automatically. If you need to continually rely on MySQL time zones, the above command should be executed every time the system time zone is updated. I'm not sure what the equivalent Windows command would be): mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql

Executing the following command loads the time zone data from the system (Unix-only. This should work fine in many cases, but there are times when it is better to use named time zones, like for not worrying about daylight savings time. When not loaded, you are limited to converting using offsets (e.g. If it returns a DATETIME (in this case 08:00:00), you have time zones loaded. If you want to test if they are loaded, try executing: SELECT CONVERT_TZ(' 12:00:00', 'GMT', 'America/New_York') It already has that privilege.By default, (at least on Debian-based installations) no time zone data is loaded into MySQL. It's just a localized human-readable string for the name of the time zone used when daylight time is in effect.Īs SetDynamicTimeZoneInformation requires the SE_TIME_ZONE_NAME privilege, you might find it easier to execute the TZUtil.exe utility with the /s parameter to set the time zone by ID. The string "Central Europe Daylight Time" is not a time zone ID. Not all Windows time zones match in English, and they certainly won't match if the OS language is not English. That the ID and the English Standard Name happen to match is purely coincidental. Daylight Name: "Central Europe Daylight Time".

Standard Name: "Central Europe Standard Time".

Display Name: "(UTC+01:00) Belgrade, Bratislava, Budapest, Ljubljana, Prague".

The string "Central Europe Standard Time" is the ID (key name) for the time zone with the following English localized strings associated with it: When found, pass that DYNAMIC_TIME_ZONE_INFORMATION structure to the SetDynamicTimeZoneInformation function to change the time zone. Instead, use the EnumDynamicTimeZoneInformation function to locate the zone with the desired ID in the TimeZoneKeyName field. It has hardcoded information about the time zone's bias and DST information.

Ignore the sample in the SetTimeZoneInformation doc. (The docs are slightly misleading in this regard, as this has been the case from Windows Vista and newer, not just Windows 7 and 8.) Use SetDynamicTimeZoneInformation instead. Don't use SetTimeZoneInformation, as it doesn't support the complete "dynamic" time zone information that is used in modern Windows.
