How to use this crate with runtime time-zones?

[jorgecarleitao]

Hi,

I have been investigating how to use this crate in the context of jorgecarleitao/arrow2#23, but have faced the challenge whereby our crate declares timezones as strings, while this one uses compile time timezones.

A simple exercise I am trying to achieve is to write the following function:

fn add_days(timestamps: Vec<i64>, timezone: &str, days: i64) -> Vec<i64>

where i64 is a timestamp represented in timezone. Do I need to match timezone to perform this calculation?

Ok, I found out; Something like

let timezone = chrono_tz::Tz::from_str(timezone)?;
timezone.timestamp(x, 0).timestamp()
