I have a shell function I use all the time to keep track of both calendar and timezones where our teams are located

  now() {
    cal -3
    echo
    echo -n "Local:       "
    date --rfc-3339=s
    echo -n "UTC:         "
    date -u --rfc-3339=s
    echo -n "New York     "
    TZ='America/New_York' date --rfc-3339=s
    echo -n "London:      "
    TZ='Europe/London' date --rfc-3339=s
    echo -n "New Zealand: "
    TZ='Pacific/Auckland' date --rfc-3339=s
  }
