bash terminal [\t] (time) is not same timezone as 'date'

view story

http://unix.stackexchange.com – In my .bashrc file I configured how I would like my prompt to be displayed. My .bashrc is sourced in .bash_profile. The command in the .bashrc file is: PS1='[\t] \u@\h is $PWD :: ' I switched the user (for me) timezone to GMT+0 using tzselect. The problem I am having is that using the date command I am getting the GMT time (which I am pleased with) but the terminal prompt is still on the system time (even after logging in and logging out), which I am not pleased with. How can I get the terminal to display the time in the time format that I, the user, am specifying? (HowTos)
