The following example converts the timestamp value in the LISTTIME column from the default UTC time zone to PST. Though the timestamp is within the daylight time period, it’s converted to standard time because the target time zone is specified as an abbreviation . However, you need to know what happens during daylight saving time in the United States. In short, the local time is advanced one hour during daylight saving time. As an example, the Eastern Time zone difference from UTC is -4 hours during daylight saving time rather than -5 hours as it is during standard time. This will add your local time zone to the datetime, and also offset the actual value by the difference in hours from utc to pst (AlanVerhagen1977.blogspot.com). To obtain your local time here in the United States, you need to subtract a certain number of hours from UTC depending on how many time zones you are away from Greenwich . The table below shows the standard difference from UTC time to local time. The following example converts a timestamp LISTTIME column from the default UTC time zone to US/Pacific time zone. The target time zone uses a time zone name, and the timestamp is within the daylight time period, so the function returns the daylight time. MyTimeConverter is a site meant to allow you to quickly convert times from one timezone to another . The site was developed as an answer to the ’95 designed sites that I found when searching for a time zone converter on Google myself. If you have a timestamp without time zone column and you’re storing timestamps as UTC, you need to tell PostgreSQL that, and then tell it to convert it to your local time zone. The following example converts the timestamp to US Eastern Daylight Time because the target time zone uses a time zone name (America/New_York) and the timestamp is within the daylight time period. The following example converts a timestamp to US Eastern Standard Time because the target time zone uses a time zone name (America/New_York) and the timestamp is within the standard time period. Daylight savings time is assumed to be one hour ahead of the given offset. Here is a conversion table to help convert UTC to your own local time zone. In the United States and Canada, this time zone is generically called the Pacific Time Zone. In Mexico, the corresponding time zone is known as the Zona Noroeste and observes the same daylight saving schedule as the U.S. and Canada. The largest city in the Pacific Time Zone is Los Angeles, whose metropolitan area is also the largest in the time zone.
