[Kst] Feature Request: Time axis in Excel numeric units

[repaul_schrott-kst at yahoo.de]

I had a look at the sourcecode of plotaxis.[h,cpp] source code.

The required formula is actually much simpler

    JULIAN_DATE = EXCEL_DATE + 2415018.5
or 

    JD18991230  = 2415018.5   // Julian Date of 30-Dec-1899 00:00:00 GMT 

    JULIAN_DATE = EXCEL_DATE + JD1899_12_30


Thanks
