I try to fix time_extends with layer and the behaivor are the same, also I
logged the postgresql & mapserver:
with this query show always the first image , at the 11:00:00, in the log of
postgresql the query has not time parameter

with this url selects first image but show the second, in this case the
query take into account time parameter

the same above but with "&mode=map" will have the same behavior than the
first url, show always the first image
when you put seconds in the url postgresql recives a query with
date_trunc('second', image_time) , If put only minute date_trunc('minute',
image_time), it seems that mapserver detect what kind of time parameter is.
It's so tricky this mapserver :/ , thanks daryl & alexander
