[rt-users] "time left" field

[Oli]

Hi,

i have a question regarding the "time left" field. Is it possible to 
configure that this field will automatically updated by the "time 
worked" field? So when an technician post his work and enters the time 
for it, that this will automatically decrease the "time left" value. 
In short time left = time left - time worked.

We are using rt 3.8.1 on a debian. If there is need for more information 
i try to gather and post it. 

Maby someone has a hint!

Thanks in advance!

Regards Oliver
