Scripting issue regarding commands with parameters

Scripting issue regarding commands with parameters

I have a need to set the timezone on WES7 clients, and created a little script to do so.

Unfortunately, I am running into quoting issues.

The command is very simple:
tzutil /s "Eastern Standard Time"

The EX command should be able to handle this, but the command itself needs to be quoted, and then you would end up with embedded quotes:

EX "tzutil /s "Eastern Standard Time""

This doesn't work. The documentation doesn't cover this scenario or discuss escaping quotes. Do I have to create a batch file that I XC over first or is there a workaround?
