Hi,

I am working in Enterprise COBOL and DB2 in Mainframes.

How do i convert a Time in (HH:MM:SS AM/PM) format to 24 hours format(HH:MM:SS). I tried using the ALTTIME function but the Schema DSN8 which this functions belongs to, is not working.

Thanks in Advance,
Siva

When you say 'not working', what kind of error message you get?

Check in SYSIBM.SYSROUTINES for an entry of ALTTIME function with DSN8. It is probably not there. You can talk to your DBAs to make that available.

Otherwise, as far as I understand, DB2 doesn't have any builtin function that can take in a time format like HH:MM:SS AM/PM

There is one HH:MM AM/PM however, if you are willing to sacrifice the 'SS'.

Hi,

Thanks for your inputs, I'll check in SYSROUTINES.
Used a query like this,
EXEC SQL
SELECT
(RIGHT('00'||RTRIM(CHAR(HOUR(IN_TIME))),2) ||
'.' ||
RIGHT('00'||RTRIM(CHAR(MINUTE(IN_TIME))),2) ||
'.' ||
RIGHT('00'||RTRIM(CHAR(SECOND(IN_TIME))),2))
END-EXEC.

The INTIME is in HH:MM:SS AM/PM format, above query converts it to 24hrs format.

Thanks,
Siva

Hmm..the HOUR function is not supposed take a TIME format with HH:MM:SS AM/PM as input as far as the manual says. But then if it works for you, great!

And thanks to you, I tried out the ALTTIME function. icon_biggrin.gif
