# Windows and IANA time zones
PostgreSQL function to convert between Windows and IANA time zone names with this prototype:
```sql
FUNCTION timezone_names(windows_tz text DEFAULT NULL, iana_tz text DEFAULT NULL, territory text DEFAULT NULL)
RETURNS TABLE(windows_timezone text, liana_timezone text, territory_abbrev text)
```
Examples:
```sql
-- List of all Windows and IANA time zones and territory codes (as to store in a table)
select * from timezone_names();
-- Data for Bulgaria by IANA time zone name
select * from timezone_names(iana_tz => 'Europe/Sofia');
-- Data for Bulgaria by Windows time zone name and territory
select * from timezone_names(windows_tz => 'FLE Standard Time', territory => 'BG');
```
In order to force a single-line result for a Windows or IANA time zone name supply `territory => '001'` as an argument.
The function uses [windowsZones.xml](https://github.com/unicode-org/cldr/blob/master/common/supplemental/windowsZones.xml), part of the [Unicode CLDR project](http://cldr.unicode.org/) as a source of data.
