How to setup bash custom prompt (PS1)

Paste to the end of your ~/.bashrc file

export PS1='\n\[\e[32m\]\t \u@\h \[\e[33m\w$(__git_ps1)\e[0m\]\n\$ '
ps1_time() {
    printf "\033[s\033[2A\033[32m%s\033[0m\033[u" $(date +%H:%M:%S);
}
export PROMPT_COMMAND="trap 'ps1_time; trap DEBUG' DEBUG"

Fix for long lines

ps1_time() {
    local s=1 c IFS=$'\n'
    for c in $BASH_COMMAND; do s=$((${#c}/$COLUMNS+1+$s)); done
    printf "\033[s\033[${s}A\033[32m%s\033[0m\033[u" $(date +%H:%M:%S);
}
export PS1='\n\[\e[32m\]\t \u@\h \[\e[33m\w$(__git_ps1)\e[0m\]\n\$ '
export PROMPT_COMMAND="trap 'ps1_time; trap DEBUG' DEBUG"
