synthID: "nlhpi", q:"Convert price request timestamp to UTC time. If the timestamp is before 22nd, 02:00:00 - use previous month's price data released on 22nd 02:00:00 i.e. if the timestamp is 21st March use the data released on 22nd Feb which is the data for Jan. If the timestamp is on/after 22nd, 02:00:00 - use current month's price data i.e. if the request timestamp is the 22nd March, use the data that was released on 22nd March which is the data for February. If 22nd falls on a weekend, the price is updated on the following Monday at 02:00:00. If the request timestamp falls before the 23rd/24th (date depends on whether the 22nd is Saturday/Sunday), use data released on the 22nd of the previous month. If the timestamp falls on/after 02:00:00 on the 23rd/24th, use the data released for this month. Find the month and year for which price should be requested. Convert timestamp to correct date format i.e, if timestamp is the 21st Mar, use the price data released on 22nd Feb. The price data released on 22nd February is the price data for January 2023.
