How to do operations with dates fields?

Got a date field that I would like to return only events that were within a specific range, from today to 15 days in the future.
To get today:
|eval timenow=now() |eval nowstring=strftime(now(),"%d/%m/%Y %H:%M:%S")
|table nowstring
04/11/2014 10:35:59

My date field is already like this:
|table "Resolution Period"
27/01/2014 23:59:59

But when I try a simple search like this:
|where "Resolution Period" > nowstring |table "Resolution Period"
I still got all events, unfiltered. Do I need to change something on the "Resolution Period"??

And How to return only events that were within a specific range, from today to 15 days in the future.???

Thanks in advance

Hi bruno_eduardo,

I would compare epoch times not human readable time stamps.

So something like this will do it:

... | eval now_time=now() 
| convert mktime("Resolution Period") AS Resolution_Period
| where Resolution_Period > now_time
| table Resolution_Period

regarding the future timestamp you can try this:

... | eval future_time=relative_time(now(), "+15d") | ...

this will return an epoch timestamp as well.

hope this helps ....

cheers, MuS
