Many countries have DST (Daylight Saving Time) during the (local) summer. Rather than listing the researchers twice, once in the standard time zone, once in the daylight saving time zone, I've chosen to list them only in their standard time zone. In the table below, a DST time zone is always one step down from the standard time zone.

All DST zone codes have footnotes added to them, specifying exactly when they will change to standard time, and I've also added the code for the standard time for that zone. On 30 October 2005 most countries in the northern hemisphere will change from DST to standard time, and countries in the southern hemisphere will change from standard time to DST.

If you want your name added to this table, please post in a conversation over at U203563. Some researchers have even been kind enough to let us know at what time they can usually be expected to be online - you will find that information in the conversations on that user page.
