[JASS] Can i ask this trigger meaning ?

[Gochill]

GetFloatGameState(GAME_STATE_TIME_OF_DAY)>=18. or
GetFloatGameState(GAME_STATE_TIME_OF_DAY)<=6. then

Thank you for read my question !

I hope to know that function ( GetFloatGamesState ) meaning what.
If you are fine, i want to know entire meaning of code.
Unfortunately i can't guess what it is and i failed to find it.

That says the in-game time is either beyond 6:00 p.m. or before 6:00 a.m.

if you did not disable blizzard.j you are better off using "not bj_dncIsDaytime".
boolean bj_dncIsDaytime
