Xamarin.Forms DateTime.Now() date does not match current date

I have a user that keeps getting an error where his DateTime.Now() timestamp is a day or two behind the current system DateTime. This application is working correctly on ~80 other devices.

Restarting the application seems to correct the issue. Does anyone have any experience with this issue?

I am accessing the System.DateTime from a static helper class, here are the variables that get the current date and time:

    public static string DateFormat = "yyyy-MM-dd HH':'mm':'ss";
    public static string ShortDateFormat = "yyyy-MM-dd HH':'mm";
    public static string DateOnlyFormat = "yyyy-MM-dd";
    public static string Today = DateTime.Now.ToString(DateFormat);
    public static string TodayDate = DateTime.Now.ToString(DateOnlyFormat);
    public static string CurrentTime = DateTime.Now.TimeOfDay.ToString();

>Solution :

Your fields(!)

public static string Today = DateTime.Now.ToString(DateFormat);

are initialized exactly once, when the program starts or the class where this definition is is first used.

You likely want to use a property instead:

public static string Today => DateTime.Now.ToString(DateFormat);

This returns a new string each time it is requested.
