There was a problem with some time zones from memory, in the uk for example 1970 had an odd daylight saving period and because 1970 is used in calculating the time values in the driver this skews the results in the driver. Using the current year fixes it when calculating times.

Maybe something to check.

This is the same as https://github.com/pgjdbc/pgjdbc/pull/133

So what I am wondering is why a small number of people see this and the rest are fine ???

What is unique about your environment. Are the server and the client on the same timezone ?

There is a problem with JDBS driver interpretation of "timestamp without time zone" values when binary transfer is on. When binary transfer is disabled for TIMESTAMP columns (binaryTransferDisable=TIMESTAMP or binaryTransfer=false) problem does not occur.

 

database version: 9.1.1

driver version: 9.2, 9.3

 

BINARY TRANSFER:

----------------

database value (TIMESTAMP):                 2014-10-26 01:00:04

bytes (AbstractJdbc2Resultset):              [0, 1, -87, 71, -77, -6, 45, 0]

long value (TimestampUtils):                    467600404000000

java timestamp (TimestampUtils):          2014-10-26 02:00:04.0                   (not OK)

 

TEXT TRANSFER:

--------------

database value (TIMESTAMP):                                 2014-10-26 01:00:04

string value (AbstractJdbc2Resultset):                 2014-10-26 01:00:04

java timestamp (TimestampUtils):                         2014-10-26 01:00:04.0    (OK)
