Question

I am new to database development and am currently working in MySQL.
I have a column that contains all the time zones for USA. I want to be able to get the current time (only time, no date) as of right now for each time zone in each row.

The TimeZone data looks like: +05:00, -03:00 etc etc etc

This is how I have attempted it. I have 2 tables, one country, one city. TimeZone is found within “city” table. I have tried to use the function sys date() but it returns the complete date and the current time on my system, not based on the time zone. Can anyone help me out? Thanks a lot

 select TimeZone, Country, sysdate() as "Current Time"  
 from city, country 
 where Country='USA' and city.CountryId= country.CountryId;

You should be able to use the convert_tz function:

SELECT CONVERT_TZ(NOW(),'-07:00', city.TimeZone) AS Time, city.Name
    FROM city, country 
    WHERE country.Name='USA' and city.CountryId= country.CountryId;

Assuming your server is in -07:00 timezone.
