Many people do not use the date directly, it is served to other machines
via other software such as ntpd.  You should be able to configure ntpd to
add an appropriate offset such that the correct date is served.
If using directly (e.g. a machine is logging data and communicating
directly with the Tbolt to get date stamps) you would have to add the
equivalent offset yourself.
