1700Z = 1800 DST. The document clearly states the meeting began at 1900, but other documents, including MT's engagement diary, clearly place it at 1800, ie 1700Z. The full file from which this item is taken can be seen here. Read other documents selected from this file.

The talks took place in the PM's study, according to a Lobby Briefing at 1935, which can be read here.

The minor annotations resemble those MT used when writing her memoirs in 1992.
