Timestamps in MySQL are generally used to track changes to records, and are often updated every time the record is changed. If you want to store a specific value you should use a datetime field.
To convert a datetime to a date, you can use the CONVERT() , TRY_CONVERT() , or CAST() function.
What is the difference between MySQL DATETIME and TIMESTAMP data type? Range − Datetime data type supports a date along with time in the range between 1000-01-01 00:00:00 and 9999-12-31 23:59:59. But timestamp data type supports a date along with time in the range between '1970-01-01 00:00:01' to '2038-01-19 08:44:07'.
Just as DATETIME , the TIMESTAMP data type contains both the date and the time in the following format YYYY-MM-DD hh:mm:ss . However, unlike DATETIME , the TIMESTAMP data type has a fixed range between 1970-01-01 00:00:01 UTC to 2038-01-19 03:14:07 UTC.
No there isn't. DateTime
represents some point in time that is composed of a date and a time. However, you can retrieve the date part via the Date
property (which is another DateTime
with the time set to 00:00:00
).
And you can retrieve individual date properties via Day
, Month
and Year
.
UPDATE: In .NET 6 the types DateOnly
and TimeOnly
are introduced that represent just a date or just a time.
I created a simple Date struct for times when you need a simple date without worrying about time portion, timezones, local vs. utc, etc.
Date today = Date.Today;
Date yesterday = Date.Today.AddDays(-1);
Date independenceDay = Date.Parse("2013-07-04");
independenceDay.ToLongString(); // "Thursday, July 4, 2013"
independenceDay.ToShortString(); // "7/4/2013"
independenceDay.ToString(); // "7/4/2013"
independenceDay.ToString("s"); // "2013-07-04"
int july = independenceDay.Month; // 7

Unfortunately, not in the .Net BCL. Dates are usually represented as a DateTime object with the time set to midnight.
As you can guess, this means that you have all the attendant timezone issues around it, even though for a Date object you'd want absolutely no timezone handling.
Create a wrapper class. Something like this:
public class Date:IEquatable<Date>,IEquatable<DateTime>
{
public Date(DateTime date)
{
value = date.Date;
}
public bool Equals(Date other)
{
return other != null && value.Equals(other.value);
}
public bool Equals(DateTime other)
{
return value.Equals(other);
}
public override string ToString()
{
return value.ToString();
}
public static implicit operator DateTime(Date date)
{
return date.value;
}
public static explicit operator Date(DateTime dateTime)
{
return new Date(dateTime);
}
private DateTime value;
}
And expose whatever of value
you want.
