How long a session lasts

How long a nexus market login lasts is decided by the service, can be changed by the service without telling anybody, and is not visible from outside. There is no way to observe it without an account, and this site has none and never will.

So there is no figure here, and there will not be one. The tiles measure this page instead, which is the board being consistent rather than the board being clever: when there is nothing to count, count the thing you actually have.

Your own experience is the only source available, and it is a weak one. You will notice roughly how long you can leave a tab before being asked to sign in again, and that observation is genuinely useful for planning your own visits.

It is not useful as a fact about the service. It reflects your browser behaviour, your own idle time, whatever your machine did while you were away, and the service configuration at that moment. A friend doing the same thing may see something different and neither of you is wrong.

• Anything you leave half finished may not be there when you come back, and you will find out by discovering it rather than by being warned.
• A tab left open is not a session left open. The tab is yours, the session is not, and the two expire independently.
• A session that ends is not a problem. It is the normal case, and treating it as a fault sends people looking for causes that do not exist.
• Planning around an assumed duration is planning around a number you made up from a handful of visits.

Do what you came to do, then leave. Not as a security ritual, but because an open session you are not using is a piece of state you are not thinking about, and unattended state is where surprises come from.

The alternative habit, leaving a tab open across a day and returning to it, is comfortable and generates most of the confusion on this panel. It is also how people end up with several tabs in different states, which is the subject of the panel on two tabs.

It is worth being explicit about why this is a refusal rather than a gap. A published session length would be one person generalising from a few visits, presented as a property of the service.

Readers would then use it. They would leave something half done because they had read that they had a certain amount of time, and the number would be wrong, and the wrongness would be discovered at the least convenient moment. A confident number here does active harm in a way that no number does not.

The same reasoning is why the board publishes no uptime, no timings and no last checked marker anywhere. It is one rule applied consistently rather than a series of separate omissions.

Word count on this panel, reading time from that word count, this panel length beside the panels either side of it, and its share of the whole board. Every one of them is countable by you from the page in front of you.

That is the reason they are here rather than a placeholder. A tile you can check yourself is a demonstration of the standard the rest of the board holds itself to, and it does the demonstrating on the panel where the thing a reader wanted is unavailable.

Why not just describe roughly how long it lasts?

Because a rough figure gets used as a precise one. The honest answer is that it varies, is not announced, and cannot be observed from here.

Is being signed out unexpectedly a sign of a problem?

Not on its own. Sessions end, and the ending is rarely announced in advance.
