it should print the entire file once with the changed fields. It works fine on your sample data in the original post.
Please show WHAT you have and HOW do you run it.

Code:
awk ' ( NF == 5 ) && ( /^\./ ) {  gsub(/[0-1][0-9][0-3][0-9][0-9][0-9][0-2][0-9][E][DS][T]/, dateblock synoptime tz, $4) ; print  } 1' dateblock=$(date +%m%d%y)     tz=$(date +%Z) synoptime=$synoptime modtest > modtest2

awk ' (( NF == 4 ) && ( /^\./ )) && ( $4 !~ /^[0-9]/ ) {  gsub(/[0-1][0-9][0-3][0-9][0-9][0-9][0-2][0-9][E][DS][T]/, dateblock synoptime tz, $3) ; print } 1' dateblock=$(date +%m%d%y)     tz=$(date +%Z) synoptime=$synoptime modtest >> modtest2

awk ' (( NF == 4 ) && ( /^\./ )) && ( $4 ~ /^[0-9]/ ) {  gsub(/[0-1][0-9][0-3][0-9][0-9][0-9][0-2][0-9][E][DS][T]/, dateblock synoptime tz, $4) ; print } 1' dateblock=$(date +%m%d%y)     tz=$(date +%Z) synoptime=$synoptime modtest >> modtest2

awk ' (( NF == 3 ) && ( /^\.T/ )) && ( $3 ~ /^[0-9]/ ) {  gsub(/[0-1][0-9][0-3][0-9][0-9][0-9][0-2][0-9][E][DS][T]/, dateblock synoptime tz, $3) ; print } 1' dateblock=$dateblock tz=$tz synoptime=$synoptime modtest >> modtest2


I have also tried it as one big awk block, but so far it's only outputting the last line of the modtest file:

(synoptime, dateblock, tz defined earlier in script)

Code:
awk 'BEGIN {dateblock=$dateblock; tz=$tz; synoptime=$synoptime}
{
     if  (( NF == 5 ) && ( /^\./ ))
     { gsub(/[0-1][0-9][0-3][0-9][0-9][0-9][0-2][0-9][E][DS][T]/, dateblock synoptime tz, $4) }

     if  ((( NF == 4 ) && ( /^\./ )) && ( $4 !~ /^[0-9]/ ))
     { gsub(/[0-1][0-9][0-3][0-9][0-9][0-9][0-2][0-9][E][DS][T]/, dateblock synoptime tz, $3) }

     if ((( NF == 4 ) && ( /^\./ )) && ( $4 ~ /^[0-9]/ ))
     { gsub(/[0-1][0-9][0-3][0-9][0-9][0-9][0-2][0-9][E][DS][T]/, dateblock synoptime tz, $4) }

     if ((( NF == 3 ) && ( /^\.T/ )) && ( $3 ~ /^[0-9]/ )) 
     { gsub(/[0-1][0-9][0-3][0-9][0-9][0-9][0-2][0-9][E][DS][T]/, dateblock synoptime tz, $3) }
}
END { print } ' modtest
