Converting Timestamp into calendar-clock time values

Dupal and other PHP open sources store time as timestamp into database.
So, while working or debugging on such DB tables, one has to convert it into calendar-clock time format (mm/dd/yy- hh:mm:ss). Reason could be anything.

For this, either write your own php code or use this tool

Unix Timestamp Converter

You should know timezone of your web application.

In drupal 6 it is in admin/settings/date-time

Now to get the GMT offset of this timezone one can use

The World Clock

Type the city name in search city field. Go to city page.

Here you can find your timezone's GMT offset.

So, both tools together helps you to undertand your db table time values.
