Could remove the timers and use GetTickCount.

pawn Код:

// Global Variable
new CommandTimeStamp[ MAX_PLAYERS ];

// OnPlayerConnect
CommandTimeStamp[ MAX_PLAYERS ] = 0;

// OnPlayerCommandText
if ( !strcmp( "/mycommand", cmdtext, true ) )
{
  if ( ( GetTickCount() - CommandTimeStamp[ playerid ] ) < 10000 ) // If difference in time is less than 10000 ms (10 seconds)
    return SendClientMessage( playerid, "You must wait 10 seconds before using this command again." );
  else
  {
    CommandTimeStamp[ playerid ] = GetTickCount( );
    
    // Your code!
  }
}
