Investigated this issue further. Currently, there's no support in GORM for any Date/Time types except timestamp with time zone
See this part of code from dialect_postgres.go:
case reflect.Struct:
if _, ok := dataValue.Interface().(time.Time); ok {
sqlType = "timestamp with time zone"
}
So basically I see two options for you:
Either use varchar(10)
in DB, and string
in Go, an simply save it as "9:00 PM" (where 10 is some number that suits you)
Or use timestamp with time zone
in DB, time.Time
in Go, and format your date part as a constant date, 01/01/1970, for example:
time.Parse("2006-01-02 3:04PM", "1970-01-01 9:00PM")
In that case you'll have to omit the date part in your presentation, but if you plan to select by date range, that could work better for you.
