System Configuration
---------------------
Architecture (example: Intel Pentium) :Intel Pentium

Operating System (example: Linux 2.0.26 ELF) : 2.2.2 (client), 2.0.35
(server)

PostgreSQL version (example: PostgreSQL-6.3.2) : PostgreSQL-6.3.2

Compiler used (example: gcc 2.7.2) :gcc 2.7.2

java full version "Linux_JDK_1.1.7_v1a_green_threads

I trust this is enough to identify the version of jdbc:
[summer(at)possum data]$ jar -tv /usr/share/postgresql/postgresql.jar

[summer(at)possum data]$ jar -tvf /usr/share/postgresql/postgresql.jar

Dates, when retrieved, are advanced by one day from what was supposed to be
stored:
