PHP s strtotime function will interpret timezone codes  like UTC   If you get the date from the database client without the timezone code  but know it s UTC  then you can append it   Assuming you get the date with timestamp code  like  Fri Mar 23 2012 22 23 03 GMT-0700  PDT    which is what Javascript code     new Date    gives     time   strtotime  dateWithTimeZone    dateInLocal   date  Y-m-d H i s    time     Or if you don t  which is likely from MySQL  then    time   strtotime  dateInUTC   UTC     dateInLocal   date  Y-m-d H i s    time

Here is a straight way to convert the UTC time of the questioner to local time  This is for a stored time in a database etc   i e  any time  You just have to find the time difference between UTC time and the local time you are interested in and then ajust the stored UTC time adding to it the difference      df    G i s       Use a simple time format to find the difference  ts1   strtotime date  df         Timestamp of current local time  ts2   strtotime gmdate  df       Timestamp of current UTC time  ts3    ts1- ts2                  Their difference   You can then add this difference to the stored UTC time   In my place  Athens  the difference is exactly 5 00 00   Example    time   time      Or any other timestamp  time     ts3     Add the difference  dateInLocal   date  Y-m-d H i s    time

First  get the date in UTC -- you ve already done that so this step would really just be a database call    timezone    UTC   date default timezone set  timezone     utc   gmdate  M d Y h i s A    print  UTC      date  r   strtotime  utc       n     Next  set your local time zone in PHP    timezone    America Guayaquil   date default timezone set  timezone     And now get the offset in seconds    offset   date  Z   strtotime  utc    print  offset   offset  n     Finally  add the offset to the integer timestamp of your original datetime   print  LOCAL      date  r   strtotime  utc     offset      n
