Hi,
kannel will send validity in utc therefore 00+ is hardcoded.
Thanks,
Alex

Hello,
I already sent this messages to the "users" mailing list, but I guess
that was not the right place for such some protocol oriented thoughts.
SMPP validity dates is specified following this time format:
“YYMMDDhhmmsstnnp”, where:
* ‘nn’ is the Time difference in quarter hours between local time (as
expressed in the first 13 bytes) and UTC (Universal Time Constant)
time
(00-48).
* 'p' is '+' or '-' depending if local time is retarded or advanced in
relation to UTC time.
It seems to me that these parameters are hard coded to "00+" in
Kannel.
Wouldn't it be nice if we could set them from the config file?
On top of that, I've seen the 'R' value as 'p' parameter. I think it's
a feature starting from SMPP V3.4
The 'R' value defines a relative validity date. It means you don't
care
anymore about server's timezones or the different servers time offset,
but just define the how long you want your SMS to be valid.
For instance, “000000000500000R”, means "5 minutes validity from when
the SMSC receives the message".
What do you think of this possibility?
I currently use relative validity, but our patch replaces the actual
"full date" behaviour. I guess it breaks compatibility with older SMPP
gateways.
Thanks for your advice.
