Hi,
I was not aware that you were in relative time before.
The only reason for switching is that it offers greater accuracy than
absolute time. There is no guarantee that SMScs are correctly synchronized
to NTP. Some users seem to objection to this. (or the UG entry). You
obviously had your reasons for switching to absolute time. Could you list
them or send me an email reference?
In kannel, in SMPP, the validity is correctly converted to calendar date
before sending out. There is no bug, and the resolution in configuration is
perefectly acceptable (seconds are an overkill).
BR,
Nikos

Hi,
I don't see why we have to switch to relative time again. Only bug in kannel
is, that validity is in minutes and not
absolute time. The same bug apply to deferred.
Thanks,

I stand corrected. bb sends in, at least in SMPP, absolute time as GMT +
validity * 60 for validity and scheduled delivery time. Not very safe or
good. Needs the server to be synchronized with SMSc, which would probably
mean both have to be ntp synchronized.
This is a defect of the SMPP spec. It defines the format of relative time
in absolute terms, instead of seconds, making it difficult to calculate
and reconstruct.
The proposed patch makes smpp work with relative time. Please test, I do
not have access to an SMSc. Let me know how it goes. I hope that all SMScs
support it. It is more accurate than absolute time, since it doesn't
require synchronization between smsc and bearerbox.
Please vote.

According to SMPP version 3.4 time can be absolute or relative. Absolute
time is default.
How it is implemented in particular software is another question. I
think that the kannel uses absolute time, at least for SMPP.
Here is comment from gw/smsc/smsc_smpp.c

/*
* check for validity and defered settings

Well, UG is wrong there. In the SMSc definitions it states:
validityperiod integer
How long the message will be valid, i.e., how long the SMSC will try try
to send
the message to the recipient. Defined in minutes.

thans for your reponce
but in SMS Push (send-sms) CGI Variables it is writen in the userguid
that to
use
the variable validity you should syncronize with smsc
contant
Optional. If given, Kannel will
inform SMS Center that it should
only try to send the message for
this many minutes. If the
destination mobile is off other
situation that it cannot receive
the sms, the smsc discards the
message. Note: you must have
your Kannel box time
synchronized with the SMS
Center.
note that i need to specify it for a specified service

Hi,
You don't need to. SMPP protocol works with validity period (relative
time).
Therefore, no absolute time is ever involved and you don't need to
synchronize.

Hi all,
I want to set validity variable so I need to syncrnize with the smsc
my question is
How can I syncronize kannel box with smsc
