Get Unix Time in Go (Time Since Epoch)

Unix time is the number of seconds since ‘Epoch’ (00:00:00 UTC on 1 January 1970). It’s a widely adopted way of representing time in a simple, uniform, manner - as it’s an integer and not a string. Because of it’s simplicity, it also used it many programming languages. In Go, you can easily access it from the time package by getting the current time, then calling the Unix() function.

Add Date Ordinals (UK Date Format) in Go

Go, despite its robust standard library, does not support ordinal dates out of the box like ‘th’ and ‘st’. This makes producing dates in the format “1st January 2000” much harder - which we use a lot here in the UK. In this post we’ll aim to show how you can make this easier. For reference, these are the options Go uses when chosing a new format: 1 Mon Jan 2 15:04:05 MST 2006 Our example below implements this for ourselves, as we create formatDateWithOrdinal() to print a given time in this format. This uses all three of the .Day() .Month() and .Year() functions within the time package, but passes the day through our extra function to add the ordinal.

How to Format Your Golang Code

Whether you agree with it or not, Go defines a code style at a language level (which I love), and not different styles per project - or having the style as an afterthought! This means there’s very little opinion or conflict when moving between projects so it’s easy. This is very important to Go, as it stresses clarity and consistency as some of the most important factors of code style. So you’ve written some code, and have been told to format it?

Convert String to Int, Int64, Uint64

This is one of those posts that won’t need a huge introduction. We want to convert a string into an integer. We’ll look at the different ways to do this (based on which sort of int you want). We’ll convert to int, uint and uint64 (though a int64 will be easy enough work out).
