The TIME Data Type

Randolph West covers the TIME data type in SQL Server:

This week, we look at the TIME data type. It is formatted as HH:mm:ss.fffffff, where HH is hours between 0 and 23, mmis minutes between 0 and 59, ss is seconds between 0 and 59, and f represents 0 or more fractional seconds, up to a maximum of seven decimal places.

With a maximum length of 5 bytes, TIME can store a value with a granularity of up to 100 nanoseconds.

I tend not to use TIME very often.  It’s useful if you need it, but I rarely find myself needing a dateless time.
