The TIMESTAMP type corresponds to the %Library.TimeStamp data type (=%TimeStamp) in InterSystems products, and the format is YYYY-MM-DD HH:MM:SS.nnnnnnnnn.
If you want to change the precision after the decimal point, set it using the following method.
1) Set system-wide

Default time precision for GETDATE(), CURRENT_TIME, CURRENT_TIMESTAMP. You can specify the number of digits in the range 0 to 9.

2) Specify with SQL function
Using the argument of CURRENT_TIMESTAMP(), you can specify the number of digits after the decimal point in the range of 0 to 9.
*The value returned by CURRENT_TIMESTAMP() is the current date and time in the execution environment's time zone.
