Wrong ts_init and ts_event value for Weekly historical bar data from IBKR

[Endura2024]

When use HistoricInteractiveBrokersClient to get weekly bar, the ts_init and ts_event value are not correct:

query IBKR directly for weekly data return:
date open high low close volume average barCount
...
4 2024-01-19 474.25 482.75 469.87 482.64 253556992.0 475.666 1270853

using HistoricInteractiveBrokersClient get
open high low close volume ts_event
4 474.25 482.75 469.87 482.64 253556992 1705622400000000000
ts_init ts_event_dt ts_init_dt
4 1706227200000000000 2024-01-18 19:00:00-05:00 2024-01-25 19:00:00-05:00

for debugging purposed, I converted the ts_init/event to NY local date time. The date returned by IBKR are the Friday, i.e. end date for the given bar, but it seems HistoricInteractiveBrokersClient treats the date returned by IBKR as starting time (ts_event). The date returned by IBKR for day, weekly and monthly bar are different from intraday bar:

• for intraday bar, such as 1min, 1hour, the datetime represents the beginning of the period
• for day, weekly and monthly bar, it return only date portion, which represents ending period for the bar, such as weekly bar use Friday date, and Monthly bar use last trading day of month
