# Release notes for Time (v0.6.0)
This marks another notable release from `v0.3.1`. For anyone of you who isn't
familiar with what this is all about, [time](https://github.com/gernest/time) is a time package for the zig
programming language. It offers a clean API to manipulate and display time,
this package also supports time zones.
## Notable changes
### Print durations in a human format
`Duration.string` returns a human readable string for the duration.
For instance if you want to print duration of one hour ,four minutes and 10 seconds.
```
const hour = Duration.Hour.value;
const minute = Duration.Minute.value;
const second = Duration.Second.value;
var d = Duration.init(hour + minute * 4 + second * 10);
warn("duration is {} \n", d.string());
```
```
duration is 1h4m10s
```
## date manipulations
### Time.addDate
You can add date value to an existing Time instance to get a new date.
For example
```
var local = time.Location.getLocal();
var ts = time.now(&local);
var buf = try std.Buffer.init(std.debug.global_allocator, "");
defer buf.deinit();
try ts.string(&buf);
warn("\ncurrent time is {}\n", buf.toSlice());
// let's add 1 year
ts = ts.addDate(1, 0, 0);
try ts.string(&buf);
warn("this time next year is {}\n", buf.toSlice());
```
```
current time is 2018-12-08 10:32:30.000178063 +0300 EATm=+419006.837156719
this time next year is 2019-12-08 10:32:30.000178063 +0300 EAT
```
Please play with the api, you can add year,month,day. If you want to go back in
time then use negative numbers. From the example above if you want to back one year then
use `ts.addDate(-1, 0, 0)`
This is just highlight, there are
- lots of bug fixes
- cleanups to more idiomatic zig
- lots of utility time goodies like `Time.beginningOfMonth`
- improved documentation
- lots of tests added
- ... and so much more
I encourage you to take a look at it so you can experiment for yourself.
All kind of feedback is welcome.
Enjoy

This is part of [time](https://github.com/gernest/time) package. I think it is cool to showcase how far the package has matured.
`calendar.zig`
```
const Time = @import("./src/time.zig").Time;
pub fn main() void {
Time.calendar();
}
```
```
$ zig run calendar.zig

Today's date is prefixed with `*` eg `*13`.
Enjoy.

# time
Time library for the zig programming language (ziglang).
In my opinion, the go programming language offers a very elegant api for dealing with time.
This library ports the [go standard library time package](). It is not 100% `1:1` mapping
with the go counterpart but offers majority of what you might need for your time needs.
# Locations and timezones
A time library isn't complete with timezone. This library supports timezone. I comes with
a parser implementation for reading timezone info from all supported platforms.

## formating timestamps with zig
Most of you are not aware of the [time package](https://github.com/gernest/time).
A new release has just landed with support for formating time into various timestamps.
### Layouts
Time is formatted into different layouts. A layout is a string which defines
how time is formatted, for example `Mon Jan 2 15:04:05 MST 2006`.
You can read more about layouts
here https://github.com/gernest/time/blob/a3d45b5f5b607b7bedd4d0d4ca12307f0d6ff52b/src/time.zig#L791-L850
I will focus on showcasing using the standard timestamp layouts that are provided by the library.
These are standard layouts provided by the library
```
pub const ANSIC = "Mon Jan _2 15:04:05 2006";
pub const UnixDate = "Mon Jan _2 15:04:05 MST 2006";
pub const RubyDate = "Mon Jan 02 15:04:05 -0700 2006";
pub const RFC822 = "02 Jan 06 15:04 MST";
pub const RFC822Z = "02 Jan 06 15:04 -0700"; // RFC822 with numeric zone
pub const RFC850 = "Monday, 02-Jan-06 15:04:05 MST";
pub const RFC1123 = "Mon, 02 Jan 2006 15:04:05 MST";
pub const RFC1123Z = "Mon, 02 Jan 2006 15:04:05 -0700"; // RFC1123 with numeric zone
pub const RFC3339 = "2006-01-02T15:04:05Z07:00";
pub const RFC3339Nano = "2006-01-02T15:04:05.999999999Z07:00";
pub const Kitchen = "3:04PM";
// Handy time stamps.
pub const Stamp = "Jan _2 15:04:05";
pub const StampMilli = "Jan _2 15:04:05.000";
pub const StampMicro = "Jan _2 15:04:05.000000";
pub const StampNano = "Jan _2 15:04:05.000000000";
```
