__During testing, the local time TimeLocal() is always equal to the server time TimeTradeServer(). In turn, the server time is always equal to the time corresponding to the GMT time - TimeGMT(). This way, all of these functions display the same time during testing.
The lack of a difference between the GMT, the Local, and the server time in the Strategy Tester is done deliberately in case there is no connection to the server. The test results should always be the same, regardless of whether or not there is a connection. Information about the server time is not stored locally, and is taken from the server.[/quote:qdo9sokh]
