Performance Considerations for Date-Time MOVEs

The format of a date-time item affects the amount of time a date-time move will take to complete. The three basic formats in order of best to worst performance are:
  1. A date-time item whose format is equivalent to a DDS supported date, time, or timestamp format. Within this group, ISO formats are generally the best.
  2. A non-locale based date-time item whose format is not part of 1.
  3. A locale-based date-time item.
