RE: Timestamps

[Peter Connell <peterc@xxxxxxxxxxxxx>]

I toyed with this as well. There was a way, I can't recall at present, but I
since I couldn't guarantee against the remote possiblity of 2 separate
processes simultaneously retrieving the same timestamp before writing a
record, I opted for using the job number as well to achieve uniqueness.
Unless multiple writes occur together in the same pgm with almost no delay
the jobno/timestamp would be unique.

David,
The reason for the accuracy is for duplicate records.  If a maintenance
program tries to update multiples records at one time and the timestamp is
our key field, we get a duplicate key message.  And yes adding one to a
counter certainly would work, but we are using an API to get our timestamp
and therefore we would have to track if the call to the API was initiated
from this commit cycle or it is a new cycle.  I just thought that using
milli seconds we might have a easier time.

        Ron,

        Why does it have to be that accurate?  It is difficult to set a
timestamp in a trigger  
        to the full precision allowed.  As this is an update, it is
obviously not being used as a 
        unique key field.  By the time you get a full length timestamp in a
trigger and set your 
        update time, it won't be the actual update time anyway.  I would
think you would be 
        just as well off to add .000001 to the time, assuming this is
occurring in one process.

        Hi All,

        We have a trigger program which updates a timestamp field in the
data file
        with the last changed time.  When a commit is done and 3 records are
        committed to the same file, all 3 have the same timestamp.  How do I
        retrieve the system time with the milliseconds in it?

        Thanks

        Ron
