+ *    After filtering de-chunked instances, remove
+ *    "Transfer-Encoding" header entirely instead of changing
+ *    it to "Transfer-Encoding: identity", which is invalid.
+ *    Thanks Michael Shields <shields@msrl.com>. Fixes PR 1318658.

+ *    Don't use localtime in parse_header_time. An empty time struct

+ *    Use gmtime_r if available, fallback to gmtime with mutex
