    1. COIf there is such a function, be very careful with it. It can lose information, as `TDateTime` can neither hold dates before `TDateTime(0.0)`, nor has it a concept of time zones or daylight saving time.

    2. CO@Mason, the part of your comment about TDateTime = 0.0 is incorrect. Setting a TDateTime value to -693593.00, for instance, results in a date of 01/01/0001 correctly being stored. Using StrToDate('01/01/0001') also correctly returns -693593.00

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
