tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

Timestamp is a data type that represents an instant in time and space. It is supported by most programming languages. However, it is not defined in the msgpack spec. The lack of built-in support for timestamp is a constant issue brought up while evaluating encodings.

The proposal is to include timestamp support in the new spec as an inter-operable extension type, defined by the spec along with Binary. It will have extension tag -2.

A timestamp is composed of 3 components:

secs: signed integer representing seconds since unix epoch
nsces: unsigned integer representing fractional seconds as a nanosecond offset within secs, in the range 0 <= nsecs < 1e9
tz: signed integer representing timezone offset in minutes east of UTC, and a dst (daylight savings time) flag
