[LDM #NJE-906346]: LDM Log Time Zone Issue

Justin,

Very odd.

Try this. Replace the file "src/ulog/Makefile.am" with the attached, new 
version and add the attached file "test_gmtime.c" to that same directory. Then 
go into the "src/ulog" directory and execute the command "make check". It 
should execute successfully and the current UTC time should be printed near the 
end of the output.
