If you run the following you get back a time that is not on par with hour timeframe.
//Returned value equals something like 23:03
Also in chart, If you count 60 bars with crosshair(click and drag) from an hour interval like 22:00 on m1 time frame the time you get at the 60th bar is 23:03 and not 23:00.
There are 60 m1 bars between 22:00 and 23:00 not 63???
There are some bars missing on the M1 chart
Ie. there were no ticks for a period of more than 1 minute, so a bar was not formed.
So between 22:00 and 23:00, 3 bars were missing , therefore only 57 bars in that 1 hour period.
So counting 60 bars from 22:00, takes you 3 bars past 23:00
