What is a Datetime2 data type?
The DateTime2 is an SQL Server data type, that stores both date & time together. The time is based on the 24 hours clock. The DateTime2 stores the fractional seconds Up to 7 decimal places (1⁄10000000 of a second). The Precision is optional and you can specify it while defining the DateTime2 column.
Should you use Datetime2?
The MSDN documentation for datetime recommends using datetime2. Here is their recommendation: Use the time , date , datetime2 and datetimeoffset data types for new work. These types align with the SQL Standard.
Should I use Datetime2 or Datetimeoffset?

What Datetime2 0?
SQL Server DateTime vs Datetime2(0) If we define fractional second precision as 0 in Datetime2, it simply means that there should be no digits for nanoseconds in the date-time value. So the Datetime2(0) data type will not have a nanoseconds value in it.
What does DateTime2 0 mean?
datetime2(0) – you don’t need fractional seconds. datetime2(1-7) – you need fractional seconds of the specified precision. datetimeoffset(0-7) – you need date and time with time zone awareness. time(0-7) – you need time only (no date) with fractional seconds of the specified precision.
What’s the difference between datetime and DateTime2?
Datetime2 was introduced with SQL Server 2008, so it is here long enough to draw some comparisons with its “older brother”. The main difference is the way of data storage: while in Datetime type, the date comes first and then time, in Datetime2, 3 bytes, in the end, represents date part!

What’s the difference between DateTime and TIMESTAMP?

What is DateTimeOffset used for?
The DateTimeOffset structure represents a date and time value, together with an offset that indicates how much that value differs from UTC. Thus, the value always unambiguously identifies a single point in time.
What’s the difference between DateTime and DateTimeOffset?
With its Kind property, DateTime is able to reflect only Coordinated Universal Time (UTC) and the system’s local time zone. DateTimeOffset reflects a time’s offset from UTC, but it does not reflect the actual time zone to which that offset belongs.
What does utcNow mean?
UtcNow tells you the date and time as it would be in Coordinated Universal Time, which is also called the Greenwich Mean Time time zone – basically like it would be if you were in London England, but not during the summer.
