Feed items stamped onto a (Y, X) of REVOTT. A pair reads TNLDY Z = 14160 + 100·(Y + X); an item is stamped onto it when its own instant, read from Nsukka on the Yg clock, lies within the variac's window of that Z. Before the feeds began, back to 2013-04-01, the window is filled at day precision with GDELT's day sources. Vary Y, vary X, or both: every pair in the request is stamped.
Every pair reads Z = Ztp + Uy·Y + Ux·X. REVOTT's own setting is Ztp = 14160.0 and Uy = Ux = 100 days; set any of them here, each unit on its own, enter Y and X below, and STAMP. Y, X and the keys themselves are never altered: Ztp and the units only place them in time.
REVOTT's setting (Ztp 14160.0, Uy 100 D, Ux 100 D). The variac's ε is counted in X units: it keeps its window in time when Ux changes, and ε follows Ux.
Z = 14160 + 100·(Y + X): REVOTT's setting. The GLOBAL tab stamps with a turning point and unit of your choosing.
The reconciled clock takes the page's stated time where it stands, else the feed's, else the moment the item was first seen, which bounds both from above.
The clock. TNLDY is read from Nsukka (WAT, UTC+01:00) on the engine's own year, Yg = 17640/48.3 days, laid on Nsukka's calendar from 1 December 00:00 and recalibrated at every Yg year (nsukka-yg-clock.js). A TNLDY passed over at a recalibration has no instant and holds no item; one met twice holds the items of both instants.
The stamp. A pair reads Z = Ztp + Uy·Y + Ux·X, and |Z(item) − Z(pair)| ≤ Ux·ε, compared exactly. REVOTT's own Ztp is 14160.0 and Uy = Ux = 100 days; GLOBAL sets others, each unit on its own, leaving Y, X and the keys as they are. The variac ε is in X units: at Ux = 100 days, 0.01 X is one day and 0.0001 X, the last digit of a key, 14.4 minutes. Pairs that read one Z share their items (in REVOTT's setting, those on one level line Y + X = constant); each pair remains its own reading. A stamp records what fell in the window, nothing more.
NULL is never zero. The feeds are read every 15 minutes while the reading computer runs; each source counts as covered for a window only if a reading of it reached back across the whole window. Before the first reading () the archive is GDELT's day sources, from 00:00 Nsukka, at day precision; a day GDELT never published is NULL. Before that there is no archive.
Sources. The JOMO SFO-WAM knowledge-server feeds (3pp-noah/jomo-sfo-wam); each article's own page is read once for the time it states, obeying robots.txt. Publishers that refuse keep their feed time. Before the feeds, GDELT's day sources (nth-member/gdelt): each day's 250 most-cited source URLs by GDELT's article counts, one per domain and per path, the day being the one GDELT ingested its archive, laid on Nsukka's calendar day as REVOTT reads it. They are one list per day, whatever feeds are chosen.
