I tried fetching data using get_timeseries() and found no lag compared to Quote data. Please see the screenshot below, the API was called at 7:13 AM (UTC time) and the latest data returned from get_timeseries() is the same time as trade time (TRDTIM_1) in Quote.
For the lag that occurred,
- you may check if the user has real-time permission on that RIC
- or it could be that there's no trading occurred during that time.
