The Under-17 World Championship in Egypt in September 1997 was used by FIFA to introduce a standardised system of timing goals, substitutions and other incidents during football matches. This system was then applied during the FIFA/Confederations' Cup 1997 as well as the World Cup in France 1998 and continues to be used for all other official FIFA competitions.
For example, if the player YOBAR scores a goal after 32 minutes and 15 seconds, it is recorded as "in the 33rd minute" and not "after 32 minutes". Thus, the goal would be recorded YOBAR (33) and not YOBAR (32).
There is also a new way to distinguish when a goal is scored in the time added on for stoppages at the end of the first half or second half. This is done by adding a "+" sign.
If a goal is scored after, for example, 46 minutes 30 seconds of the first half, before half-time, this is recorded as YOBAR (47+). If a goal is scored in the second minute of the second half, this is recorded as YOBAR (47).
In the time added on for stoppages at the end of a match played without extra time, a goal scored after 92 minutes 45 seconds is recorded as YOBAR (93).
However, if the match goes then to extra time, that goal must be recorded as YOBAR (93+), to show that it was scored before a goal scored in the first minute of extra time (91).
