Representation of Date/Time Values in Headers
Updated: June 29, 2016
Azure storage services follow RFC 1123 for representation of date/time values. This is the preferred format for HTTP/1.1 operations, as described in section 3.3 of the HTTP/1.1 Protocol Parameters specification. An example of this format is:
Sun, 06 Nov 1994 08:49:37 GMT
The following format is also supported, as described in the HTTP/1.1 protocol specification:
Sunday, 06-Nov-94 08:49:37 GMT
Both are represented in the Coordinated Universal Time (UTC), also known as Greenwich Mean Time.
