I tried the Tamriel clock add-on but it only tells me what day it is today if it started on 4 Rain's Hand 2e582. There are no options to adjust manually … at least I didn't see it.
When I start a new toon I always start at mid-day on 4 Rain's Hand 2e582 (ie April 4, 2014) - so only 3 hours of playtime before midnight (I count 6 hours play for a Tamriel day).
No matter how I play it at the start I always loose 15 days in Coldharbour at the start of the Prophet storyline.
On my current toon created December 15, 2019 I am at level 44 and I have /played 2 days 17 hours 5 minutes and I am on Middas, 30 Rain's Hand 2e582 (on January 8, 2020) - thanks to the New Year Festival boost.
Is there a clock add-on that is adjustable so I can shown with precision at install the time of day and date I want ?
The infamous arcane explosion in the Imperial City that happened in the Spring of 2e579 — a night of storms, and trembling terrain — as related by the Chorrol Crier, mentioned by Chancellor Abnur Tharn in his "Eulogy for Emperor Varen" and explained by Lyris of Skyrim in the first volume of her "Chronicles of the Five Companions", and others, I am sure. The “Soulburst” happened at the same time as a big piece of Aetherius fell to Nirn. Coincidence? It was the first major piece of Aetherius to fall in five hundred years.
Then I met the Prophet on 4 Rain's Hand 2e582.
