Humans have different ways to measure time, but the Gregorian calendar is by far the most used calendar and it is used as an international standard. One of the few things that have united humanity, it is how they measure time, they have and use normally Coordinated Universal Time (UTC, UT or GMT), including the "weird" time zone of India. It is a good thing that humanity have reached acceptable levels in terms of synchronization.
Currently, we don't have yet our own measures of time (time control,clock), we use UTC for scheduling (schedule). At the moment, we post every day in endchan (using daily cycles in UTC).
