See The World Clock for list of current times around the world, and which places are observing DST at the moment (marked by * in The World Clock).
Daylight saving time is also called summer time or daylight savings time. When DST is not observed, it is called standard time, normal time or winter time.
This list displays a brief (but not complete) overview over which countries that observed DST during 1999.
Current country names, rather than historic country names are displayed, so the list could contain countries that did not exist at the time.
Detailed information is available for the first half of 1999 and the second half of 1999.
