Windows 10: Time correct but date often wrong

    Time correct but date often wrong

    I have a brand-new computer with a clean install of Win 10 which I've been using for about 10 days now. While the system time is always correct, every couple of days when I boot the system the date will be off by a day or two, usually ahead. I have reset the date in the BIOS and keep resetting it in the Date and Time screens of Settings. I have experimented with synchronizing both with NIST and Windows time servers. So far nothing has solved the incorrect date problem. Since it's a new box it seems unlikely the CMOS battery is at fault, and even if it were that should result in incorrect times as well as dates. Where should I look to correct this problem?

    I would talk with the vendor ASAP. You may need to exchange the machine within your 30 day free typical time window.

    Sounds like the problem occurs when the system was off and then powered up? Is the system overclocked?

    No, it's not overclocked. The problem usually occurs on boot but I believe once occurred on wakeup. However, I guess I don't understand why either the BIOS or Windows 10 would show a correct time but an incorrect date. Aren't both derived from a binary counter, such as the number of seconds from some base? If so, it seems very unlikely that only the date would be incorrect.

    This is really far-fetched, I apologize if you think this is too silly to post, but as I have "resolved" a same kind of issue in Windows 8 for an American online friend of mine, I thought in the spirit of trying to find a reasonable explanation that the only thing to lose in posting something this silly is my reputation. That's since long gone, no reason not to post

    This online friend of mine asked in Skype a few years back if I knew why his laptop shows a wrong date. I do not remember which dates I am talking about nor do I remember the exact date when we Skyped but let's for examples sake say that it was early December when we spoke on Skype.

    He mentioned that "now Windows is telling me it's April 12th, yesterday it told it was March 12th".

    Together we found out that he had accidentally set the computer location as United Kingdom instead of United States, resulting Windows calendar defaulting to European formats and showing the date as 4/12/201X (day-month-year) and the previous day as 3/12/201X instead of American format 12/4/201X and 12/3/201X (month-day-year).

    I am not implying this might be your case, I am just saying that because I know from my own experience that things like this can happen, I decided to post this, however far-fetched it is.

    Heck, I would not consider that to be far fetched at all.

    This happens quite easily because UK and US are next to each other in the drop down menus. For example in setting Windows 10 location in settings:

    When you open the drop down menu, UK is just before US:

    A millimeter / fraction of an inch mouse movement when doing a selection and you might not notice you have selected wrong country.

    This mistake might go unnoticed as long as the date is 12th or less; after 13th you already realize the format is wrong

    Thanks, but I have checked carefully and my Date & Time settings are (and have been) correctly set to: UTC-5:00 Eastern Time (U.S. & Canada), and the Region & Language to United States.

    Just one more check, takes a few seconds of your time.

    As the time zone, computer location and time & date settings can all be set independently, it's worts to check the default formats. Simply press WIN + R to open the Run dialog, type control intl.cpl and hit Enter to open the region module of Control Panel and check that both Short date and Long date formats match your preferred way to present the date:

    If not, click Additional settings button and change them as you wish:

    In Customize Format dialog you can either select a pre-defined format or edit them manually using following abbreviations:

    • d = day of the month without leading zero
    • dd = day of the month without leading zero
    • dddd = day of the week
    • MMM = three letter abbreviation for month (APR, AUG, DEC and so on)
    • MMMM = full name of the month
    • yy = year with two last digits
    • yyyy = year with four digits
    • You can also add separators as you wish (hyphen, slash, comma, period, colon and so on)

    Thanks for the suggestion. However, I checked those settings and they appear to be OK.
