In KRL How can I get the current year, month, and day? - time

Question

I am working on an application in which I need to get the current year, month, and day. Is there a way to get this information in the pre block of a rule?
Can I get this data as a string or a number or both?
There are currently time functions documented on http://docs.kynetx.com/docs/Time but none of them seem to work for what I am trying to do.
Is there a way to set the timezone when getting this data?

Answer 1

I was able to do it using strftime which appears to be an undocumented feature so use with caution.
ruleset a60x518 {
meta {
name "date-test"
description <<
date-test
>>
author "Mike Grace"
logging on
}
rule testing {
select when pageview ".*"
pre {
retTime = time:strftime(time:now({"tz":"America/Denver"}), "%c");
month = time:strftime(time:now({"tz":"America/Denver"}), "%B");
year = time:strftime(time:now({"tz":"America/Denver"}), "%Y");
day = time:strftime(time:now({"tz":"America/Denver"}), "%d");
}
{
notify("time",retTime) with sticky = true;
notify("month",month) with sticky = true;
notify("year",year) with sticky = true;
notify("day",day) with sticky = true;
}
}
}
App run on example.com twice. Once with the timezone set to New York and onother time set to Denver
I used this site http://www.statoids.com/tus.html to get the correct strings to use for the timezone. I have no idea if they all work. I just found this site and tried a few and they worked so use with caution.

Perhaps the docs got reverted. For convenience, here is the documentation for strftime:
time:strftime()
Convert a datetime string to a different format
Usage
time:strftime(`<string>`,`<format>`)
Valid format arguments to strftime follow the POSIX strftime conventions.
Samples
time:strftime(xTime,”%F %T”) # 2010-10-06 18:15:24
time:strftime(xTime,”%F”) # 2010-10-06
time:strftime(xTime,”%T”) # 18:19:29
time:strftime(xTime,”%A %d %b %Y”) # Wednesday 06 Oct 2010
time:strftime(xTime,”%c”) # Oct 6, 2010 6:25:55 PM
The other time functions:
time:now()
Current datetime based upon user’s location data
Usage
time:now()
time:now({“tz” : <timezone>)
time:new()
Create a new RFC 3339 datetime string from a string (allows some flexibility in how the source string is formatted)
Usage
time:new() # Equivalent to time:now()
time:new(<string>)
Valid formats for the datetime source string can be found in ISO8601 (v2000).
time:add()
Add (or subtract) a specific number of time units to a source string
Usage
time:add(<string>,{<unit> : n})
