Ah, I was overthinking things.

SimpleDateFormat extends DateFormat. DateFormat defines setTimeZone().

TimeZone is an instance of java.util.TimeZone, and easiest obtained from an ID.

from java.util import TimeZone
from java.text import SimpleDateFormat

#for tz in TimeZone.getAvailableIDs():
#	print tz

now = system.date.now()

eastern = TimeZone.getTimeZone("America/New_York")
pacific = TimeZone.getTimeZone("America/Los_Angeles")

sdf = SimpleDateFormat("yyyy-MM-dd HH:mm:ss ZZZ")
print sdf.getTimeZone().getID()
print sdf.format(now)

sdf.setTimeZone(eastern)
print sdf.getTimeZone().getID()
print sdf.format(now)

sdf.setTimeZone(pacific)
print sdf.getTimeZone().getID()
print sdf.format(now)

Here in California, that gets me:
