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 ?
First I give my toons a prequel to their story ... doing all the miscellaneous quests of their province of origin. Then they follow the playstyle of "What Order Should I Do ESO's Story Arcs? - A Guide"
