The IANA time zone database maps a name to the named location's historical and predicted clock shifts. This database is used by many computer software systems, including most Unix-like operating systems, Java, and the Oracle RDBMS; HP's "tztab" database is similar but incompatible. When temporal authorities change DST rules, zoneinfo updates are installed as part of ordinary system maintenance. In Unix-like systems the TZ environment variable specifies the location name, as in TZ=':America/New_York'. In many of those systems there is also a system-wide setting that is applied if the TZ environment variable isn't set: this setting is controlled by the contents of the /etc/localtime file, which is usually a symbolic link or hard link to one of the zoneinfo files. Internal time is stored in timezone-independent epoch time; the TZ is used by each of potentially many simultaneous users and processes to independently localize time display.

The IANA database works by connecting names to what information about the location?
Answer: historical and predicted clock shifts

The "yo yo" in the opinion polls continued into 1992, though after November 1990 any Labour lead in the polls was rarely sufficient for a majority. Major resisted Kinnock's calls for a general election throughout 1991. Kinnock campaigned on the theme "It's Time for a Change", urging voters to elect a new government after more than a decade of unbroken Conservative rule. However, the Conservatives themselves had undergone a dramatic change in the change of leader from Thatcher to Major, at least in terms of style if not substance. From the outset, it was clearly a well-received change, as Labour's 14-point lead in the November 1990 "Poll of Polls" was replaced by an 8% Tory lead a month later.

What year did Kinnock call for a general election?
Answer: 1991

In the century after the death of Osman I, Ottoman rule began to extend over the Eastern Mediterranean and the Balkans. Osman's son, Orhan, captured the northwestern Anatolian city of Bursa in 1324, and made it the new capital of the Ottoman state. This Ottoman conquest meant the loss of Byzantine control over northwestern Anatolia. The important city of Thessaloniki was captured from the Venetians in 1387. The Ottoman victory at Kosovo in 1389 effectively marked the end of Serbian power in the region, paving the way for Ottoman expansion into Europe. The Battle of Nicopolis in 1396, widely regarded as the last large-scale crusade of the Middle Ages, failed to stop the advance of the victorious Ottoman Turks.

What city was captured from the Venetians in 1387?
Answer:
Thessaloniki
