Problems with UTC Timestamp

[<Mar...@ml...>]

Hi,

i have problems with an attribute that uses the syntax utc time syntax.
i generate the time with the following code line

#Timestamp
$timestamp = `date +%y%m%d%H%m%SZ`;

when i try to add the content to the utc time atrtibute with

 $ldap->modify( $dnldap, replace => {IPTimestamp => $timestamp});

i alway get an error in the log like 'invalid syntax'

2002-10-16-13:43:54.019+00:00--V2 Modify--bindDN: xxx --client: xxx
:7809--connectionID: 2--received: 2002-10-16-13:43:54.015+00:00--Invalid syntax

can anyone help me and tell me where the failure is ? am i generating the
timestamp in a wrong way ? is there another possibility to generate a timestamp
?
is the way i fed the ldap wrong ?

many thanks for help
greetings

Martin
