Hellow eweryone!

In MQL have function iTime https://docs.mql4.com/series/itime

***

datetime iTime (string symbol, int timeframe, int shift)
Returns Time value for the bar of indicated symbol with timeframe and shift. If local history is empty (not loaded), function returns 0.
For the current chart, the information about bars open times is in the predefined array named Time[].
Parameters:
symbol      -      Symbol the data of which should be used to calculate indicator. NULL means the current symbol.
timeframe      -      Timeframe. It can be any of Timeframe enumeration values. 0 means the current chart timeframe.
shift      -      Index of the value taken from the indicator buffer (shift relative to the current bar the given amount of periods ago).
Sample:

  Print("Current bar for USDCHF H1: ",iTime("USDCHF",PERIOD_H1,i),", ",  iOpen("USDCHF",PERIOD_H1,i),", ",
                                      iHigh("USDCHF",PERIOD_H1,i),", ",  iLow("USDCHF",PERIOD_H1,i),", ",
                                      iClose("USDCHF",PERIOD_H1,i),", ", iVolume("USDCHF",PERIOD_H1,i));

I need analog iTime function for JForex, for example getBarStart https://www.dukascopy.com/client/javadoc ... od,%20long)

Consider using getBar method:

IBar bar = getBar(instrument, period, OfferSide.BID, shift);
long time = bar.getTime();
