Difference between GMT, GMT+0, GMT-0, GMT0 on Unix
time, unix
Solution
I think they are all the same, or at least have the same values.
Yoo can see all here: TimeZones
Problem
Under `/usr/share/lib/zoneinfo` I can see the following 4 different types of info for `GMT` ``` GMT GMT+0 GMT-0 GMT0 ``` Are there any differences between these 4 types of `GMT` zone times? If so, what are the differences?
