You know how you need to set up a timezone for your phone or laptop when you first configure it?
Most computer systems usually have a local timezone configured so that they can coordinate the system clock with the rest of the world via NTP.
In the Go time
package this local timezone is modelled using the time.Local
location. In this code snippet we will see how to change a time.Time
from a different location to the time.Local
location.
Before we dive in, itβs good to know how time.Time
values represent time instants. Learn more here.
Change Location to Local
Converting a time.Time
to time.Local
is done using the Local
method on the time.Time
type.
For example, below we change a time from UTC+3
to the local timezone. The local timezone depends on the system configuration, in the demo environment below it happens to be UTC
.
In this example, we initially have a time value t1
in the UTC+3
location (a fixed timezone).
We then call t1.Local()
to create t2
in the local timezone (UTC
in this case).
t1
and t2
represent the same time instant, but they will have different clock readings. t2
will read 3 hours before t1
.
Run the example to verify this.
