Variable explanation

What does this part in the following code ?

if [ ".$t" != . ]; then
$t shows some time values for getting the response, but why .$t and what does the . after the !=

Code:
t=$(time -p wget --quiet --post-data='username=xxx&password=xxxx&id=xxxxxx' --no-check-certificate --output-document=/tmp/sms-status_out --timeout=30 "https://www.xxx.de/gsm/status.php" | perl -ne 'print int($1 * 1000) if /^real (\S+)/')
if [ ".$t" != . ]; then

thx

Alex
