Why Does Go's `time.Now()` Sometimes Return 2009-11-10 23:00:00 UTC?

Why Does Go time.Now() Return 2009-11-10 23:00:00 0000 UTC?

Running the time.Now() function in Go version 1.3 on Windows 7x64 consistently yields the date and time of 2009-11-10 23:00:00 0000 UTC. While this phenomenon is expected on the Go Playground (due to its fixed time setting), its occurrence on local machines can be puzzling.

The reason behind this unusual behavior is that this specific date and time marks the birthday of the Go language. Go's creators, Rob Pike, Robert Griesemer, and Ken Thompson, published the initial public prototype of Go on November 10, 2009.

This timestamp is used within the Go runtime as a "dummy" value to assist in debugging. If the system time is not set correctly or cannot be determined, the runtime uses this fallback timestamp to ensure that the program can still function.

Upgrading to Go version 1.3 and restarting your computer have been known to resolve this issue for some users. However, it's important to note that if the system time remains unset or inaccurately configured, the time.Now() function may continue to return the "Go birthday" timestamp.

The above is the detailed content of Why Does Go's `time.Now()` Sometimes Return 2009-11-10 23:00:00 UTC?. For more information, please follow other related articles on the PHP Chinese website!

Wrapping Errors in Go: Adding Context to Error ChainsApr 28, 2025 am 12:02 AM

In Go, errors can be wrapped and context can be added via errors.Wrap and errors.Unwrap methods. 1) Using the new feature of the errors package, you can add context information during error propagation. 2) Help locate the problem by wrapping errors through fmt.Errorf and %w. 3) Custom error types can create more semantic errors and enhance the expressive ability of error handling.

Understanding Go's error InterfaceApr 27, 2025 am 12:16 AM

Go's error interface is defined as typeerrorinterface{Error()string}, allowing any type that implements the Error() method to be considered an error. The steps for use are as follows: 1. Basically check and log errors, such as iferr!=nil{log.Printf("Anerroroccurred:%v",err)return}. 2. Create a custom error type to provide more information, such as typeMyErrorstruct{MsgstringDetailstring}. 3. Use error wrappers (since Go1.13) to add context without losing the original error message,
