Format String with Timezone?

I see the FormatString class explicitly states:

SimpleDateFormat specifies that we do not support:

Era designator, BC/AD (G)
Day of week in month (F)
Hour in day, 24-hour, with 1-based instead of normal 0-based numbering (hours are 1-24) (k)
Hour in day, 12-hour, with 0-based instead of normal 1-based numbering (hours are 0-11) (K)
Milliseconds (S)
Timezone (z, Z, X)

Just wondering if there is some way I can display the timezone of my DateTime (java Date object) with the timezone as a String?
