Spacetime allows your team to set their work hours and automatically detects and handles time zone conversions for you.
It moves conversations like “what time is it for you?” and “when do you start your day tomorrow?” into a simple dashboard and Slack bot. Simply message the bot (@spacetime 3pm) and get the answers you need.
yourtime.zone automatically translates the time of an event into the visitor's local time. Great for organizing global events, such as webinars or live-streams.
Team Time is a simple Slack command to know the local time of every user in a channel
You have a remote working team and trying to schedule a meeting? Sounds very good, but wait, first you need to look up for the time of colleagues from the internet. Search: "London time", "San Francisco time" etc.
