Figures are built from what connected systems have delivered, so they reflect the last delivery rather than the present moment.
The schedules differ by source
Each connection runs on its own cadence, and the cadence is set partly by what the institution supports.
Banks release transactions on their own timetable, which is why a payment made this morning may not appear today even where everything is working normally. Accounting systems and field service systems deliver on their own schedules again.
So two figures drawn from two sources can be current to different points in time, which is one reason they can differ — see the unified ledger.
Where to see it
Sources lists every connection with the last time data arrived from it. That timestamp is the answer to how current any figure is, and it is more useful than any general statement about frequency.
What a stale timestamp means
A source whose last delivery is older than its usual interval is the thing to check first when a figure looks behind — see a connection stopped bringing data in.
Calculated figures
Metrics and reports are recalculated after new data arrives rather than continuously. A figure can therefore lag its underlying transactions briefly even after those transactions have landed.
What does not arrive on a schedule
Anything entered by hand, and anything from a system that is not connected. Cash taken and not banked exists nowhere until it is recorded.
Confidence
Where a source is behind far enough that a figure would mislead, the figure is held back rather than shown — see how confident a number is.
