Vertica VerticaDayTimeInterval precision is stored wrongly
Precision is always a guideline for representation of data. Data are always stored with a specific precision, which is the maximum precision supported by the driver (and the engine of course). The precision that was used by the user to insert data is not stored in the database, as it is only useful when representing … Read more
Why does “%-d”, or “%-e” remove the leading space or zero?
Python datetime.strftime() delegates to C strftime() function that is platform-dependent: The full set of format codes supported varies across platforms, because Python calls the platform C library’s strftime() function, and platform variations are common. To see the full set of format codes supported on your platform, consult the strftime(3) documentation. Glibc notes for strftime(3): – … Read more
Timezone.now() vs datetime.datetime.now()
Just always use timezone.now(). Django now has timezone support which requires timezone ‘aware’ datetime objects. datetime.now() will return a timezone naive object, whereas timezone.now() will return a timezone aware object. Read more about Django timezones
Formatting ToShortDateString to dd/MM/yyyy
ToShortDateString does not have an overload which takes any parameter. If your ToShortDateString() returns MM/dd/yyyy format, that means your CurrentCulture has this format in it’s ShortDatePattern property. You can always use custom formatting for that like with proper culture like; TextBox2.Text = DateTime.Today.ToString(“dd/MM/yyyy”, CultureInfo.InvariantCulture);
In C#, what is the difference between comparing two dates using tick and just as it is
Is this a more accurate way of comparing DateTime? Not in the slightest. In fact, that is how the > operator is implemented internally. From the .NET Reference source: public static bool operator >(DateTime t1, DateTime t2) { return t1.InternalTicks > t2.InternalTicks; } Someone might have thought they were being clever by skipping the one … Read more
Ordering nullable DateTime in Linq to SQL
This is a bit of a hack, but it appears to work with Linq to SQL: return from ju in context.Job_Users_Assigned where ju.UserID == user.ID orderby ju.Created ?? DateTime.MaxValue descending; So I’m substituting the maximum possible DateTime value when the actual “Create” value is null. That’ll put all the null values at the top. Another … Read more
DateTime.ParseExact() does not grok 24-hour time values?
“hh” is the 12-hour clock format (01 to 12). You need to use “HH” for a 24 hour clock. DateTime dt = DateTime.ParseExact(time, “HH:mm”, CultureInfo.InvariantCulture);
