Changeset 74122 in vbox for trunk/src/VBox/Runtime/common/rest/RTCRestClientApiBaseOci.cpp

Timestamp:

Message:

IPRT/rest: When we generate X-Date header we use RTTimeToRfc2822.
RFC2822 (RFC5322) marks "GMT" as obsolete, but RFC7231 explicitly
specifies literal "GMT" in the grammar (7.1.1.1), so replace final
"-0000" or "+0000" with "GMT" to make the server happy.
