Re: Displaying dates in X-Axis

[Software FX]

The AF_DATETIME format is expects date in "Variant Time" format.  You can 

use Windows API function: 

SystemTimeToVariantTime() 

To convert from a System time format (SYSTEMTIME) to a variant time. The 

following is Microsoft definition of a Variant Time from MSDN: 

" A variant time is stored as an 8-byte real value (double), representing a 

date between January 1, 100 and December 31, 9999, inclusive. The value 2.0 

represents January 1, 1900; 3.0 represents January 2, 1900, and so on. 

Adding 1 to the value increments the date by a day. The fractional part of 

the value represents the time of day. Therefore, 2.5 represents noon on 

January 1, 1900; 3.25 represents 6:00 A.M. on January 2, 1900, and so on. 

Negative numbers represent the dates prior to December 30, 1899."
