Latest Update
I completely rewrote the Clock - Tamriel Standard Time
It has now a much better performance, a pretty code background and many more features.
Check it out!
This legacy version should still work for a long time, but will not receive any updates anymore.

Overview

This addon Clock - TST adds a completely customizable and moveable label to the game which shows you the current date and time of Tamriel and of Earth (linked to your system time, thus it is accurate where ever you are).
Additionally, it also shows the current state of the moon and the remaining time to the next phase.

Updates

The last update 1.0.0 brings you a fixed Fake Lore Date and an improved fragment handeling (no more warnings when opening the menu). The FLD will show you the current week day, day and month month in the real world with a lore name.

Update 0.7.8 added independently sizeable moon and phase labels with a customizable look of moon label independent of the clock label. It has a improved moon alignment inspired by Kenza. it also is now fully translated into French (all thanks to Fifish).

With update 0.7.6 comes a Japanese translation thanks to @BowmoreLover from the ESOUI community.
Together with the new localisation, Clock can now set to show 0 am instead of 12 am at midnight with the 12h setting.

Since 0.7.2 also with Russian localisation! (next to English and German).

With Update 7 a new background feature was added. The Clock - TST never looked that good before. Check it out.
Additional to that and a few bug fixes, you can now have your real time next to the Tamriel time instead of beneath.

You can use this addon together with Harven's Dwemer Clock to get the in-game Time as a fantastic looking, animated clock. Install both addons then right-click on the Dwemer Clock and click "Use Tamriel Standard Time Clock" option. You can change the size of the Dwemer Clock by clicking on it (left mouse button) and then scrolling with your mouse wheel over the Clock.

Check out kerb9729's Addon for Clock - TST: Midnight. It will show you the time until midnight.

Follow the Clock on GitHub to always get the latest beta/alpha Version (caution: unstable)
I will release every stable build here as soon as possible!
If you like an offline desktop application of the Clock to see the current time in Tamriel where ever a PC is, search no further and look here (still an alpha Version)

Features

This AddOn will show you the current time in Tamriel.
It is displayed on the Interface wherever you want it to be - completely movable.
You are also able to set the size, font and style of the clock to your liking.

The time in Tamriel is not a fact.

There is not function in the API which gets us the length back.
Many people right now are trying to figure out how long a day is.
Zenimax Online stated in their FAQ that the time is a bit less than 5h, but after many tests, I am sure it is 5,83h long.
If you agree with me or not is up to you.
You are able to customize the length of the day easily in the Clock - TST settings.
This can be done to a precision of seconds.

The time could be off after a maintenance or something else.
With the settings menu or commands you can choose one out of four times to synchronize the clock.
For example, you see the sun right under your South needle of the compass.
You are sure that it is noon right now.
No problem: Just write /cl noon in the chat or use the "Noon is now!" button in the settings to sync your clock.

The best way to sync your Clock is to set the clock to noon at noon and wait a day or more (in-game).
Then set your time (at noon again) so that your clock shows exactly 12:00.
When this is done you should have a perfectly synced clock
Noon is best because you can see the sun and you have a compass
So just wait until the sun is right under you South sign at your compass.

Right now, the settings and the Clock is localized in English, German and Russian.

If you are from the US or any other country which uses a 12-hour clock, you are able to change the clock to that format too. You can even hide the am/pm signs.
Of course you can use the formats: 12h or 24h wherever you are from.
You can also hide the 0 before a single number: 01:12 -> 1:12.

I personally love to see the seconds pass by. It is fun to see if they reach the zero or step over it (because of the game to real time ratio). It is like the screensaver of a DVD player... you have to watch for some reason.
If they distract you too much - like me - or you just don't want to see them, just disable them.
You can disable to show seconds in the settings menu.

You can let the Clock AddOn show you the current moon phase and the time to the next one.
This feature is like the time not based on a fact but on an adjustable algorithm.
After many months of studying it, I am sure the one cycle is 30 Tamriel days long, but you can still change the length of the different phases.
You can customize the length of a moon phase at the settings menu.

Clock does not stop there.
You can also let the Clock show you the current lore date on your screen either as a real calculated date or a fake one representing the current real date as a lore date.

The look of the time and date are fully customizable.
Write a String like this in the text field in the settings:
_DDD, _D day of _MMM _YY _hh:_mm:_ss

It will return you a date looking like this:
Fredas, 4th day of First Seed 2E 582 07:09:08

If you want the Clock will also show you the current real date and time as customizable as the lore time and date.

TL;DR
Clock - TST gives you a fully customizable lore- (and real-) date and time system with moon cycle integration.

If you want a new feature to be added too, feel free to suggest it here.

The panel can be called with writing the command /clsettings in the chat.

ABOUT THIS LISTING

This page describes Clock - Tamriel Standard Time - Legacy by Tyx. The description and screenshots are the author's own, imported from their listing on ESOUI on 26 October 2026: https://www.esoui.com/downloads/info241-Clock-TamrielStandardTime-Legacy.html

Mythiq.net hosts no files for it. The download button goes straight to the release file on cdn.esoui.com, so you are downloading from the author's own host, not from a copy of ours.

The download count, rating and comments on this page start at zero and count Mythiq.net only. The source's own figures are not copied here — they measure a different site, and a number that cannot be checked against our own ledger is not worth printing.

API VERSION

Built for ESO API version 5.3.5. After a patch the game marks add-ons built for the previous API as out of date; the "Allow out of date add-ons" checkbox in the add-on menu loads them anyway, and most work.

LIBRARIES

Many ESO add-ons depend on a shared library — LibAddonMenu-2.0 above all — which is installed separately, exactly like an add-on. A dependency that is missing shows as the add-on simply not appearing in the list.

CONSOLE

Add-ons are PC and Mac only. There is no way to load them on console.

1. Download the archive with the button on this page and unzip it.

2. Move the unzipped folder into your add-ons directory:

Windows — Documents\Elder Scrolls Online\live\AddOns

macOS — ~/Documents/Elder Scrolls Online/live/AddOns

3. Start the game, and at the character select screen click Add-Ons.

4. Tick the add-on. If it is greyed out and marked out of date, tick "Allow out of date add-ons" at the top of the same panel.

5. Log in. Most add-ons need a /reloadui after they are first enabled.

UPDATING

Delete the old folder first. ESO loads everything it finds, and two copies of one add-on is the usual cause of "an add-on has produced an error" on login.
