How to stop Jackson altering datetimes when deserialising them

I'm trying to retrieve objects with a date field via a get request to my spring boot app. The dates are correct in the database, correct when debugging, but are altered by 1 hour when jackson deserializes them.

in class

@JsonFormat(pattern = "dd-MM-yyyy HH:mm")
private Date matchDate;

In application.properties

spring.jackson.deserialization.adjust-dates-to-context-time-zone=false

I have no idea why it is altering them, I want jackson to deserialise the dates exactly as they are

The documentation for that setting says,

"If enabled, contextual TimeZone will essentially override any other TimeZone information; if disabled, it will only be used if value itself does not contain any TimeZone information."

So, since your serialized format does not indicate a time zone, that setting will have no effect on your deserialization.

My suggestion is, if possible, always include a time zone when passing serialized dates around - that way, there is no question about how to interpret the value.
