Re: QWCCVTDT - Convert Date and Time Format API

Andy,

You are definitely on the right track.  QWCCVTDT was enhanced in V5R3 to 
support time zone parameters so that you can request a conversion from one 
time zone to another.  The daylight saving time adjustment is built in 
based on whether or not the source/target time zones are defined to 
support DST (with an optional parameter to indicate how to handle 
duplicate input time values like 1:05AM when "falling back".  The API will 
handle both past and future time values (though see the API Usage Notes 
for details on the range of valid dates as the range varies depending on 
the time formats you are using).

A CL example converting from Central to Mountain would be:

PGM 
DCL        VAR(&RCV) TYPE(*CHAR) LEN(20) 
CALL       PGM(QWCCVTDT) PARM(*YYMD '20050407140000000' + 
                       *YYMD &RCV 0 QN0600CST QN0700MST ' ' 0 '0') 
ENDPGM

QWCCVTDT - Convert Date and Time Format API






Am I on the right track on using the API QWCCVTDT to get what the date and 

time is from one time zone to another? Can I look at future dates and 
times?
How do I factor in daylight saving time?

Anybody happen to have an example on how I could do it if I can with this 
API?

Thanks
