You have created the procedure named sp1new using the time zone string AMERICA PACIFIC. The HELP PROCEDURE output for sp1new looks like this.
HELP PROCEDURE pa.sp1new ATTRIBUTES; Transaction Semantics TERADATA Print Mode N Platform LINUX Character Set ASCII Default Character Data Type LATIN Collation ASCII SPL Text Y Version Number 09 Default Database PA Warning Option Y Creation Timezone -07:00 Creation Timezone String AMERICA PACIFIC
Suppose you then alter procedure sp1new, recompiling it at time zone GMT ‘01:00’.
ALTER PROCEDURE pa.sp1new COMPILE AT TIME ZONE ‘01:00’;
The HELP PROCEDURE output for sp1new now looks like this. Because you specified the time zone using GMT terminology rather than a time zone string, Teradata Database does not report a time zone string.
