SMSG_LOGIN_SETTIMESPEED

Client Version 1, Client Version 2, Client Version 3.0, Client Version 3.1.0, Client Version 3.1.1

Tells the client what the datetime is and how fast time passes.

The client also asks for the datetime with CMSG_QUERY_TIME and gets a reply from SMSG_QUERY_TIME_RESPONSE, but this does not appear to change anything in the client.

Despite sending this as the very first message after the client logs in it will still send a CMSG_QUERY_TIME.

SMSG Header

Offset	Size / Endianness	Type	Name	Description
0x00	2 / Big	uint16	size	Size of the rest of the message including the opcode field but not including the size field.
0x02	2 / Little	uint16	opcode	Opcode that determines which fields the message contains.

Body

Offset	Size / Endianness	Type	Name	Comment
0x04	4 / Little	DateTime	datetime	Current server datetime. Running the client with `-console` verifies that this message in this format sets the correct datetime. SMSG_QUERY_TIME_RESPONSE will not set this.
0x08	4 / Little	f32	timescale	How many minutes should pass by every second. vmangos/cmangos/mangoszero set this to 0.01666667. This means that 1/60 minutes pass every second (one second passes every second). Setting this to 1.0 will make the client advance one minute every second.
