A couple of weeks ago, I wrote about Álvaro Ramírez’s time-zones package. It’s a package that expands on the built in world clock function by allowing cities to be added and deleted on the fly and by allowing the target time to be adjusted forward or backward.
When I wrote about it, it had just been released and was not yet on Melpa. Now, thankfully, Ramírez has added it to Melpa and made some enhancements, such as implementing DST and UTC. The original Irreal post got a couple of comments from people who have installed it and they seem happy.
Ramírez is an independent developer and provides apps such as time-zones as a public service. You can download and use it for free but it’s also important to support his efforts. The best way of doing this, I think, is by buying one or more of his paid apps such as Journelly, which I’ve written about many times. I use it constantly, several times a day and, at this point, couldn’t live without it. You’ll be helping Ramírez and yourself by getting a copy. If you don’t want to buy one of his apps, you can become a sponser.
