time problem in django, maybe related to daylight savings time adjustment

[Zhou Heng]

Please look at the image below:

The time in django is one hour later than the actual time (18:43 vs 19.43). I guess it may be because django forgot to hangle daylight savings time adjustment. How to fix this problem (so that django can adjust DST automatically, not manually after a few months when DST is not in effect in EDT time zone)? Thank you!
