Date operation

Hello all!

I have a problem, I've date in this form: @2010-12-29T17:05:43.000000+01:00

How can I add, for example, 10 days?

Thanks, bye

So I guess your using the local-time package then? Try:

(timestamp+ date 10 :day)

Thanks for reply.
Yes I use local-time package, this fn:

(local-time::universal-to-timestamp (get-universal-time))

The fn (timestamp...) don't work .

Thanks very much,

bye

UPDATE:I solve so:

(local-time::timestamp+ (local-time::universal-to-timestamp (get-universal-time)) 10 :day)

Thanks very much

Why not just decode-universal-time and encode-universal-time?

In this case he is using a library of time & date routines that store time in a specialized structure (basically just two unsigned 32's).

Read Eric Naggum's The Long, Painful History of Time for the 'why' of it.
