What’s the correct way to convert `Dates.unix2datetime(mtime(fpath))` to a datetime with the correct time zone for my system? I get a time 5 hours in the future, so I assume it’s returning UTC.

```julia

julia&gt; Dates.unix2datetime(mtime(fpath))
2021-01-31T22:46:14.370

julia&gt; Dates.now()
2021-01-31T17:46:23.646

```

Posting the answer from the slack discussion.

For this particular case, there was a requirement to only use functions in `Base` (which doesn’t include the `Dates` stdlib, or the `TimeZones` package)

Using functions only in `Base`:

```julia
julia> Base.Libc.strftime("%FT%R%Z", mtime(fpath))
"2021-02-01T01:15CET"
julia> Base.Libc.strftime("%FT%R%z", mtime(fpath))
"2021-02-01T01:15+0100"

```
