StartTime

Purpose

For the Graph Object, this sets the starting date and daily start time when used in conjunction with DateTimeMode, AutoXData, DeltaX, and DeltasPerDay. It is important that this value include the date value along with time. In other words, the value should be larger than 1 and not just a fraction value.

For the Scientific Graph Object this property sets the daily start time when used in conjunction with SpecialDateTimeMode, EndTime, and DateTimeMode.

Comments

VB, Access, and FoxPro store date/time data as the number of days since 12/31/1899.

Delphi v1 stores date/time data as the number of days since 1/1/0001.

Note that Delphi v2 and later uses sgVBDateTime rather than sgDelphiDateTime.

In all cases, the fraction portion of date/time format represents the fraction of a day.

You can use PEcreateserialdate if you need to convert to a compatible date/time format. Visual Basic and Delphi users should not have to use this function.

Refer to Chapter 7, Question 19 for more information about this property.
