I needed to know these for my current project. I found the following here (http://www.alexcurylo.com/blog/2009/01/29/nsdateformatter-formatting/) which was originally posted elsewhere and credit given but that page no longer exists. I figured I’d keep a copy here so I’m sure to always have it available.

_datePicked.text = dateString;

Result 1

Written by Scott Rowley

Note that this man page is regarding date version ‘date (GNU coreutils) 8.4’, your mileage may vary when using other versions.

I’m going to expand this section to include examples of every entry from the man page. Note that some examples include additional commands to demonstrate the information we are working with.

SYNOPSIS
date [OPTION]… [+FORMAT]
date [-u|–utc|–universal] [MMDDhhmm[[CC]YY][.ss]]

DESCRIPTION
Display the current time in the given FORMAT, or set the system date.

-d, –date=STRING

date

date -d "1 year ago"
Mon Jan 30 10:08:33 CST 2012

Web Dev> pChart WriteValues text color

Jun07
2012

Written by Scott Rowley

Just a quick post since I started toying around with pChart 2.x to add emailed reports to my osTickets Reports MOD. This took me awhile to locate and that was including 20 minutes of googling failing me.

In order to change the font color of the WriteValues (the values that show up over your generated charts). You can modify the numbers in the following file
pChart/class/pRadar.class.php

322

323

324

$ValueR = isset($Format["ValueR"]) ? $Format["ValueR"] : 0;
$ValueG = isset($Format["ValueG"]) ? $Format["ValueG"] : 0;
$ValueB = isset($Format["ValueB"]) ? $Format["ValueB"] : 0;

Setting the above to 0’s instead of 255 will change the text from white to an easier to read black.
