asterisk users - Jul 2010 - STRFTIME function declared in globals context

I'm trying to declare a few date-related global variables to ease my
dialplan.  When I declare the following in the [globals] context of
extensions.conf, I get unexpected results:

YEAR = ${STRFTIME(${EPOCH},,%Y)}
MONTH = ${STRFTIME(${EPOCH},,%m)}
DAY = ${STRFTIME(${EPOCH},,%d)}
TIMESTAMP = ${STRFTIME(${EPOCH},,%Y%m%d-%H%M%S)}

If I evaluate these variables in the dialplan later, using

exten => 7777,n,Verbose(${TIMESTAMP} - ${YEAR} - ${MONTH} - ${DAY})

My output is as follows:

    -- Executing [7777 at phones:3] Verbose("SIP/2625-0000d5f0",
"Tue Jul 13
11:08:42 2010 - Tue Jul 13 11:08:42 2010 - Tue Jul 13 11:08:42 2010 - Tue
Jul 13 11:08:42 2010") in new stack
Tue Jul 13 11:08:42 2010 - Tue Jul 13 11:08:42 2010 - Tue Jul 13 11:08:42
2010 - Tue Jul 13 11:08:42 2010

However, the following line:

exten => 7777,n,Verbose(${STRFTIME(${EPOCH},,%Y%m%d-%H%M%S)} -
${STRFTIME(${EPOCH},,%Y)} - ${STRFTIME(${EPOCH},,%m)} -
${STRFTIME(${EPOCH},,%d)})

evaluates with what I expect:

    -- Executing [7777 at phones:4] Verbose("SIP/2625-0000d5f0",
"20100713-110853 - 2010 - 07 - 13") in new stack
20100713-110853 - 2010 - 07 - 13

Is what I'm trying to do possible?  It seems like it's at least
recognizing
that I'm trying to grab a date, but it's not taking the date format
parameters that I want.

You don't state which version you are on (These things change from 1.2 to
1.4 to 1.6/8), but that being said, you would probably more likely to
succeed doing Set(GLOBAL) in an isolated context instead of using the
[global] context for this bit of voodoo.  Looking forward to a better answer
(folks like to correct my shots across the bow).

Try adding "preload => func_strings.so" to modules.conf

When you load the dialplan, do you see the global variables getting set?
That would at least tell you whether the problem lies at the point where the
values are loaded into memory, or later, at evaluation time.
