Multiple HTTP header fields store timestamps.
For example a response created on May 15, 2015 may contain the header
Date: Fri, 15 May 2015 15:34:21 GMT. Since the timestamp does not
contain any timezone or leap second information it is equvivalent to
writing 1431696861 Unix time. Rust’s SystemTime is used to store
these timestamps.
This crate provides two public functions:
parse_http_date to parse a HTTP datetime string to a system time
fmt_http_date to format a system time to a IMF-fixdate
