Daylight savings and business rules

Daylight savings and business rules

This past Sunday, most of the US observed Daylight Savings Time and moved our clocks one hour ahead. Daylight Savings Time (DST) is a case-study in how bad business rules never go away. Consider:

  • DST was implemented first during WWI and then implemented as federal law in 1966. A classic case of "We've always done it this way."
  • You should always seek to simplify business rules. But DST is not simple. With the exception of internet-connected clocks, you have to manually reset all of your clocks. In the US this is calculated to cost $2 BILLION annually.
  • DST manages TO the exception, another business rule no-no. One intent of the law was to provide more daylight because of the high cost of energy (specifically high oil prices). Oil prices (and energy costs in general) are dramatically lower than they were when these laws were enacted.

Daylight Savings Time is a waste of time (no pun intended) and money and provides little to no value.

How many of your business rules do the same?
