Using TZ and other UNIX environment variables

Use the ENVAR runtime option in your FTPD start procedure to set environment variables for the FTP server. For information about using the ENVAR runtime option to set environment variables, see z/OS XL C/C++ Programming Guide. The following example shows how to use ENVAR to specify environment variables in your FTPD started procedure:
//FTPD   PROC MODULE='FTPD',PARMS=''                       
//FTPD   EXEC PGM=&MODULE,REGION=4096K,TIME=NOLIMIT,       
//      PARM=('POSIX(ON) ALL31(ON)',                        
//           'ENVAR("TZ=EST")/&PARMS')
