It does account for timeshifts, the figures released initially are the overnights (excluding timeshifts), whilst the timeshift data is gathered over the following 7 days to produce the final figures 8 days later:

“PVR, DVDR and VCR playback and catch-up VOD viewing via TV set-top boxes is reported if it takes place within 7 days of the original broadcast. This viewing (known as timeshift viewing) is then added to the live data to produce the final, minute-by-minute consolidated audience, available 8 days after the original transmission date. Consolidated data is the ‘BARB Gold Standard’ that is used by the industry to report and trade on.”

“When a household agrees to join the panel their home has all their television sets, PVRs, DVDRs, VCRs etc. electronically monitored by a meter. Each piece of equipment that is connected to each TV set in the home is also connected to the BARB meter, which electronically monitors the equipment and determines which one is feeding the TV screen at any point and what it is doing. Over 30,000 devices, including equipment that is identified but not measured by BARB (games consoles, for example) are connected into BARB meters. Each TV in a home is connected to its own meter which holds an electronic record for the set. The meter is a small box which is put close to each television set and connected to it. The meter automatically identifies the channel that the panel member is viewing.”

also, from that same link:
Quote:
“All panel household residents and their guests register their presence when in a room with a television set on (the BARB definition of television viewing). Each individual panel member does this by pressing the button allocated to them on each meter handset. An LED screen on the front of the meter reminds panel members periodically to register their presence if they have not already done so. Whenever a panel member leaves a room they de-register their presence. The metering system monitors all registrations made by each individual for each television in the home.”
