none of them seems not giving me an idea to solve the problem.
If anyone can help, it would be grateful.
I'm using cron by a user (non wheel/admin) to rsync everyday during

My shell script is as follows.
I make up the proper command by the script. The user is authenticated

The problem is an edge-case comparison in datetime.c:glibc_fix(). This
generates a date like "Jan 32", which validate_tm() catches and NAs.

...mfortable using the *apply functions for vectorizing loops

operation, which uses values evaluated in an offset of the loop vector.
Here is my example using a for loop approach:

dat$value <- sin(dat$yday*2*pi/365)+rnorm(nrow(dat),sd=0.5)

UK Daylight Savings
A quick fix for anyone running into this problem:
load_schedule was crashing cron_trigger.rb#160, and I found that for
triggers like "0 20 5 * * * *" it was putting in 32 for the date (even
though its Mon Mar 31 04:16:21 BST 2008). Something to do with switching to
day light savings I think, which concludes after 2am. I patched it by adding
day = 31 if day == 32
on the line before.

the day not time. Can anyone suggest what is the better way to find the
julian date with date and time ?
