Description of problem:
If you setup a password policy (subtree in my case) with a passwordmaxage = x,
and then change the password of a user, it will have a passwordexpirationtime =
x - 3600.

For example, passwordmaxage setup to 1day from the console would actually
reflect a passwordexpirationtime in 23 hours.

Version-Release number of selected component (if applicable):
Directory server 1.2.2
Console framework 1.1.3

How reproducible:

Steps to Reproduce:
1. Create a subtree password policy
2. Set "Password expires after 1 day"
3. Change the password of a user under this subtree
4. Check this user advanced properties

Actual results:
The passwordexpirationtime will be approximately "now + 23h"

Expected results:
The passwordexpirationtime should be "now + 1day"

Additional info:
Maybe it's a problem in the timezones. I have my timezone setup to
Europe/Paris, which is GMT+1 ... could it be the reason ?
