Everyones game is the same. In Morrowind it normally didn't take long to finish the storyline and everything, but some people slept alot to let Creeper and TMM recharge money so imagine you wake up after one such 24h jump and realise that the date stated is already two months after the start of Oblivion, and you haven't even defeated Dagoth Ur yet. Now to some people that might not mean anything but it is the kind of inaccuracy that bothers many and would inevitable affect the way the lore timeline was planned.
This is true, and an issue that can't really be solved, because I know when I played Oblivion and heard that the Nerevarine went to Akivir, I thought "There is no way I'd go to Akivir, I was planning on going to the Black Marsh to start my traveling through Tamriel. Until I settled down in seclusion back in Vvardenfell." Morrowind doesn't change throughout the year because it was such an old game and on such a grand scope, adding that much more detail to it just wasn't possible at the time, not showing the year is also acceptable as many more people would be bothered that it was there and inconsistant then if they just omitted it.
All that being said, there will always be things to nit pick about, but we have to respect the sheer amount of work that went into these amazing games, where you have total freedom to do whatever you please, litterally even with the construction set, and such small things should be easy for fans of the series to ignore, or fix if they really think it should have been implemented, as we have that freedom.
