Strange behaviour of RWTime Class

[coolKK]

I have one doubt about RogueWave's RWTime Class ....

I am seeing some strange results when I am trying to find out when the DST starts and ends on different years.
I am using HPUX Itanium m/c and the time zone I am using is MET-1METDST.

This is the program which I am running on my HPUX Itanium m/c :
-------------------------------------------------------------------
#include <rw/rwtime.h>
#include <rw/rwdate.h>
#include <rw/rstream.h>

int main(){
RWTime d1(RWTime::beginDST(2008, RWZone::local()));
std::cout << "Start of DST, 2008: " << d1 << std::endl;
RWTime d2(RWTime::endDST(2008, RWZone::local()));
std::cout << "End of DST, 2008: " << d2 << std::endl;

RWTime d3(RWTime::beginDST(2009, RWZone::local()));
std::cout << "Start of DST, 2009: " << d3 << std::endl;
RWTime d4(RWTime::endDST(2009, RWZone::local()));
std::cout << "End of DST, 2009: " << d4 << std::endl;

RWTime d5(RWTime::beginDST(2010, RWZone::local()));
std::cout << "Start of DST, 2010: " << d5 << std::endl;
RWTime d6(RWTime::endDST(2010, RWZone::local()));
std::cout << "End of DST, 2010: " << d6 << std::endl;

RWTime d7(RWTime::beginDST(2011, RWZone::local()));
std::cout << "Start of DST, 2011: " << d7 << std::endl;
RWTime d8(RWTime::endDST(2011, RWZone::local()));
std::cout << "End of DST, 2011: " << d8 << std::endl;

RWTime d9(RWTime::beginDST(2012, RWZone::local()));
std::cout << "Start of DST, 2012: " << d9 << std::endl;
RWTime d10(RWTime::endDST(2012, RWZone::local()));
std::cout << "End of DST, 2012: " << d10 << std::endl;

return 0;
}
--------------------------------------------------------

and the output is
---------------------------------
Start of DST, 2008: 03/28/08 03:00:00
End of DST, 2008: 10/31/08 02:00:00
Start of DST, 2009: 03/28/09 03:00:00
End of DST, 2009: 10/31/09 02:00:00
Start of DST, 2010: 03/28/10 03:00:00
End of DST, 2010: 10/31/10 02:00:00
Start of DST, 2011: 03/28/11 03:00:00
End of DST, 2011: 10/31/11 02:00:00
Start of DST, 2012: 03/28/12 03:00:00
End of DST, 2012: 10/31/12 02:00:00
---------------------------------------------
Note : Current calander year of the underlyng OS is 2010.

I have observed that output is showing the DST Start date and end date of the year 2010 even if I a pass
the year as 2008 or 2009 or 2011 or 2012.


I am using HP-UX IA [11.31] system and the TimeZone is MET-1METDST.

Could you please help me in this regard as soon as possible ?

The output is dd/mm/yy, in which case it's correct. Haven't you tried looking at the source to see what it's doing?

I have not used RW before but code I have seen would be thus:

RWTime d1(RWTime::beginDST(2008, RWZone::local()));
std::cout << "Start of DST, 2008: "  << RWDate(d1) << " " << d1 << std::endl;

Hello kbw,

The ouput is in mm/dd/yy format.
If you see the program, I have simply used the Rogue Wave interfaces.
And Rogue Wave is a Third Party Product for me so I cann't access their source code.

Hello Grey Wolf,

What ever suggestion you had give is not helping . It is giving the same output.

[kbw]

If you think the output is incorrect, what do you think it ought to be?

[coolKK]

As per the DST rules of underlying OS,The output should be

---------------------------------
Start of DST, 2008: 03/30/08 03:00:00
End of DST, 2008: 10/26/08 02:00:00
Start of DST, 2009: 03/29/09 03:00:00
End of DST, 2009: 10/25/09 02:00:00
Start of DST, 2010: 03/28/10 03:00:00
End of DST, 2010: 10/31/10 02:00:00
Start of DST, 2011: 03/27/11 03:00:00
End of DST, 2011: 10/30/11 02:00:00
Start of DST, 2012: 03/25/12 03:00:00
End of DST, 2012: 10/38/12 02:00:00

Have you not looked at the source code?

I can't, I've not used Tools.h++ in about 10 years.
