Number to Date/Time

Description

Converts a number to a date/time format.

Monarch Data Prep Studio converts numbers to dates by considering the numeric value as the number of days (and fractions of days) since a specific "zero" date/time.

Monarch Data Prep Studio uses 1900-01-01 00:00:00 as its "zero" date/time. Thus:
