How to Construct a time.Time Object with a Specified Time Zone Offset?

Constructing Time.Time with Time Zone Offset

In this scenario, you've successfully parsed a date from an Apache log and obtained information such as the year, month, day, hour, minute, second, and timezone. To construct a time.Time that includes the specified time zone offset, you cannot utilize time.Local or time.UTC.

Using time.FixedZone()

To resolve this challenge, you can leverage time.FixedZone(). This method allows you to create a time.Location with a fixed time zone offset. For instance:

loc := time.FixedZone("myzone", -8*3600)
nativeDate := time.Date(2019, 2, 6, 0, 0, 0, 0, loc)
fmt.Println(nativeDate)

This code constructs a time.Location named "myzone" with an offset of -8 hours, then uses it to create a time.Time with the specified date and time.

Parsing a Time Zone Offset

If the time zone offset is provided as a string, you can utilize time.Parse() to parse it. Employ a layout string that exclusively contains the reference zone offset:

t, err := time.Parse("-0700", "-0800")
fmt.Println(t, err)

This code captures the time zone offset as a time.Time object.

Alternative Solution

Alternatively, you can modify your existing code to incorporate the time zone offset as follows:

t, err := time.Parse("-0700", "-0800")
if err != nil {
    panic(err)
}

nativeDate := time.Date(2019, 2, 6, 0, 0, 0, 0, t.Location())
fmt.Println(nativeDate)

This solution first parses the time zone offset as a time.Time object, then uses its Location() method to set the time zone for the time.Time you're constructing.
