Answers.Text: I have never seen PGN files with FIDE time control. I guess if it is a major FIDE standard chess competition then they know by default what the time control is and so there is no need to specify. It is a shame because if FIDE defined an addition to the PGN standard for this then it would become the standard.

  time per move is also called playing with increments or playing with Fischer Bonus after the 11 th World Chess Champion Bobby Fischer who championed the system. Playing with increments has become the standard in chess. Options 10-14 have a Bonus setting in the last period only (and Time settings in preceding periods). Options 15-21 have Bonus settings in all periods. Note that according to FIDE rules the clock can no longer be operated in Bonus settings when one of the players runs out of time in the last period. The clock then freezes and a blinking flag will be shown.</p>

  This method was named after chess world champion Bobby Fischer: “Fischer Bonus” called FISCH in this manual. In this method a certain amount of time is added after each move. If players use less time per move than the set bonus time, then the time on the clock will be higher after the player has

  As far as I can see from the [standard](http://www.saremba.de/chessgml/standards/pgn/pgn-complete.htm#c9.6.1) it is allowed in the first period only if there is only one period. Specifically it is allowed only in the last period.

  From what I have found out from studying the [PGN Specification](https://github.com/username_2/pgn-spec-commented/blob/main/pgn-specification.md#961-tag-timecontrol), I think that the PGN spec allows to have the following:
  
  * `40/5400+30:1800+30`
    + Start with 90 minutes
    + for the first 40 moves,
    + add then another 30 minutes for the rest of the game.
    + In both periods, use 30 seconds increment.
  
  So it would be possible to have different increments (for whatever reason) in your tournament.

The clock then freezes and a blinking flag will be shown.
