Rails 3.1.8 strange timezone behaviour. subtracting dates.to_i gives zero, ruby says dates are different
by tayles in Coding

I'm upgrading from rails 3 to 3.1.8 (and onwards). A couple of my tests are failing, one of which seemed at first glance to be because of the change from mysql2 gem (0.2.x to 0.3.x). However, it gets a little stranger. Here's what's happening.

Query to find records where a date is between start and end dates, where the dates might be reset to 0
by Brazil in Databases

We have weekly recurring events in our application, and have decided to store the start and end times for each event as the number of seconds from the beginning of the week (Sunday 12am). This makes querying, sorting, etc. much easier.


However, there is one small problem: If we want to get the event that is happening at a time near the week reset, that event could bridge that gap, a

Extracting dates from a Microsoft Excel file when dates are in many different formats
by Jon Riegel in Programming Languages

I have been given an excel file with dates in a column for about 17000 rows. The problem here is that the dates are not reliable and the cells have varying formats. Some are formatted as plain text, some are in the "general" format, yet others are in one of several available date formats.
