[mdb@yel mdb]$ date +%Z
MET
[mdb@yel mdb]$ TZ=Asia/Calcutta date +%Z
   
[mdb@yel mdb]$ TZ=Asia/Garbage date +%Z
   
[mdb@yel mdb]$ AAA=`TZ=Asia/Garbage date +%Z`;echo "'$AAA'"
'   '
[mdb@yel mdb]$ AAA=`TZ=Asia/Calcutta date +%Z` ; echo "'$AAA'"
'   '
[mdb@yel mdb]$ AAA=`TZ=Asia/Calcutta date +%Z` ; echo "'$AAA'" > i
[mdb@yel mdb]$ od i

[mdb@yel mdb]$ cat i
'MET'
[mdb@yel mdb]$ uname -a
sn5176 sn5176 9.0.2.2 sin.0 CRAY Y-MP
[mdb@yel mdb]$ 

So, for unrecognized zones, three spaces are produced for the timezone
on the CRAY Y-MP system.
