Valid timestamp format

abdulrafi · Posted: Thu May 30, 2013 9:34 pm

Hi,

I would need a help on to identify if a field contains a valid timestamp format or not.

I do have a requirement where I get a timestamp value in a variable and I need to check if its in the correct format or not.

The actual timestamp format is fo 26 bytes: yyyy-MM-dd-HH.mm.ss.ffffff

Should I check if there is a '-' on 5th,8th,11th position and '.' in 14th,17th,20th position ?. Will it be the correct way to check it ??

Please advice.

Thanks
Abdul Rafi

Hello,

To be accurate/complete, you must test every part of the entire field. Merely checking the "-" and "." delimiters provides little value. . .

What about a month, day, hour, minute, second that are numeric, but invalid?

Same with year, and leap year.

wherre are you getting this timestamp from DB2..????

Try to do a SET or SELECT FROM SYSDUMMY1 using the value you have

So you dont need to bother about source information

Yup, that will be ok if the code already uses DB2 . . .

The following previous post, shows the use of the Assembler TIME macro, returning a date-format of C'CCYYMMDD' and a time-format of C'HHMMSSTHMIJU', with "U" representing microseconds. If you don't have DB2, then this should suffice -

Hi Bill,

I believe the TS wants to validate a timestamp that has arrived in the code . . .

You can verify the format as well as the contents by calling LE Callable Service routine "CEESECS".

A value returned by "CEESECS", in the first two-bytes of the 12-byte "Feedback Code" parameter, which is not X'00's should be considered an error.

HTH....
