Sessions and time of day

time(timeframe, session) is the bar's timeframe start ("D", "W" starting Monday, "M", "60"), or na when the bar is outside session. Sessions look like "0800-1600", "2200-0600", or "0800-1600:23456" for chosen days (1 = Sunday), all in UTC. timeframe.change("D") is true on the first bar of each new day, and timeframe.in_seconds("60") converts a timeframe.

Where it differs from TradingView

ta.ema starts from the first value (like Pine). The built-in EMA indicator starts from an SMA. The two agree after a few hundred bars.
ta.pivothigh and ta.pivotlow report a pivot only once its right-hand bars exist (rightbars late), so they never see ahead. Plot with offset = -rightbars to put the mark on the pivot bar.
ta.kc uses an EMA of the true range. The built-in Keltner indicator uses ATR.
