A TDateTime value is encoded a double-precision floating point value. It is encoded in accordance with the Microsoft Excel specification, also used in the Variant type of Mi-crosoft's VB and COM technologies:TDateTime. TDateTime is stored as a double, the integer part representing days and the fractional part being fraction of a day.

Datetime is a common data type in data science projects. Often, you'll work with it and run into problems. I found Pandas is an amazing library that contains extensive capabilities and features for working with date and time. Example 4 - Storage Size. The datetime data type has a fixed storage size of 8 bytes. The datetime2 on the other hand, can be either 6, 7, or 8 bytes, depending on its precision. When using 3 decimal places, datetime2 uses just 7 bytes, which means it uses less storage space than datetime (with more accuracy).The TDateTime type holds a date and time value. It is stored as a Double variable, with the date as the integral part, and time as fractional part. The date is stored as the number of days since 30 Dec 1899. Quite why it is not 31 Dec is not clear. 01 Jan 1900 has a days value of 2.A TDateTime value is a double with the date encoded in the integer part and the time encoded in the fractional part. So, the closest thing to a 'null date' you can get is probably 0. Hence, simply test ADate <> 0 to test if the date is 'null'. C++ (Cpp) TDateTime::Day - 30 examples found.
