TraderTogami:
Right, so if I use TimeCurrent() without any datetime argument in the EA, then in the strategy backtester it will use the broker time? I assume you can't get local time in the strategy backtester, right? Thanks for the reply. 

yes broker's current timezone, but note that broker timezome switch along with day light saving, which won't happen automatically in backtest

That is irrelevant for most strategies, as the downloaded historical data already has the DST changes baked into the bars timestamp. There is no need to compensate for it under normal conditions if the strategy does not require aligning to specific exchange sessions.
