Migrate Date Field To High Precision (Data Management)

Summary

Migrates date fields in a table to high precision.

Usage

Caution:

This tool modifies the input data. See Tools that modify or update the input data for more information and strategies to avoid undesired data changes.

• High precision date fields support millisecond time.

Caution:

Once a date field is migrated to high precision, it cannot be reverted to a standard precision date field.

• The default format in which information is presented in high precision date fields is mm/dd/yyyy hh:mm:ss.fff with a specification of AM or PM.
