Symptoms:
	PHCO_25214:
	( SR:0000000000 CR:JAGab20870 )
	When  environment  variable  TZ is not  set,  the  variables
	tzname   and   timezone   is  set  to  hard   coded   values
	corresponding to Eastern Standard Time.
	JAGab20870.

Defect Description:
	PHCO_25214:
	( SR:0000000000 CR:JAGab20870 )
	When the variable TZ is not set in the environment, in HP-UX
	it defaults  to EST5EDT  which is the east coast time in US.
	This poses problem in the  environment of the processes that
	(a) are started by init(1m)
	(b) clear their environment (e.g. login (1), sendmail(1m) )
	The hard coded value is inappropriate for any timezone other
	than east coast of US and the  difference  is  difficult  to
	track for countries like Australia which  frequently  update
	their daylight timing rules.

	Resolution:
	When the environment  variable TZ is not set, tzset() checks
	the default file  /etc/default/tz for the timezone value and
	sets timezone values based on that.
	The file /etc/default/tz contains the timezone value set by
	tzset() when the environment variable TZ is not set. The
	format for the file is same as TZ format without the prefix
	"TZ=".  Please check environ(5) for TZ format.
	The order of TZ setting is as follows.
	1) if the environment variable TZ is present, it takes the
	   precedence.
	2) if TZ is not present, then the value contained in
	   /etc/default/tz is used for default.
	3) if /etc/default/tz is not set, then the default value is
	   equivalent to EST5EDT (Eastern Standard Time) of US.
