Although I guess something like this would do it ?

UPDATE sensor_values ts = ts - interval (1 hour) WHERE ts BETWEEN ('2014-03-30 01:00', '2014-10-26 02:00')

Hi I have an issue with adjusting a timestamp.

I have a table  like

CREATE TABLE sensor_values
(
      ts timestamp with time zone NOT NULL,
      value double precision NOT NULL DEFAULT 'NaN'::real,
)

It was intended that ts timestamps would be the time we wanted to store in UTC.
Clients would adjust their times to UTC before entering into the database.


Unfortunately some values have been added with BST times.
The DB thinks  they are UTC times but are an hour out this time of year.

Is the a way to adjust those times ? Ie offset the summer times back an hour ?

Thanks
