DatCh doesn´t work right

[imendez]

Hi, this code returns a series with a wrong initial date:

TimeSet tms = C-D(1)*M(1)-D(25)*M(12);
Serie sr = SubSer(CalInd(In(y1999, y2007), Diario), y1999, y2007);
Date f = First(sr);
Serie sr_d = DatCh(sr, tms, FirstS);
Date f_d = First(sr_d);

The variable "f_d" is y1998m12d31 instead of y1999.

I think this bug can be related to bugs #79, #154 and #354.

Note: I have tested this code under this versions:
TOLBase: 1.1.5. (cvs trunk)
TOL: 1.1.5. (Feb 15 2007 13:53:01)

Regards.

Sorry but y1999 = y1999m01d01 is not a date of tms = C-D(1)*M(1)-D(25)*M(12)

So DatCh(sr, tms, FirstS) cannot start in a date that doesn't belong to tms.
Standard behaviour in this case is to search the previous date in tms, it's to say 1998m12d31.

If you are agree I will set to INVALID this bug

Thanks to report anywhay

In the same way, last date of sr_d is y2007m01d02 due to y2007 is not a date of tms.

A new test has been added to check this behaviour

Yes, I agree you. I apologize for the inconvenience.

In relation with Bug 526, the test of this bug must be changed due to last date of sr_d cannot be y2007m01d02 but y2006m12d31 due sr has no data after y2007m01d01
