Bugfix
* Switch to milliseconds as the unit for ticket creation and reception time
instead of seconds. That avoids rounding errors when computing the age of
tickets compared to peer using a millisecond clock (observed with GnuTLS).
Fixes #6623.

/**
* \def MBEDTLS_SSL_TLS1_3_TICKET_AGE_TOLERANCE
*
* Maximum time difference in milliseconds tolerated between the age of a
* ticket from the server and client point of view.
* From the client point of view, the age of a ticket is the time difference
* between the time when the client proposes to the server to use the ticket
* (time of writing of the Pre-Shared Key Extension including the ticket) and
* the time the client received the ticket from the server.
* From the server point of view, the age of a ticket is the time difference
* between the time when the server receives a proposition from the client
* to use the ticket and the time when the ticket was created by the server.
* The server age is expected to be always greater than the client one and
* MBEDTLS_SSL_TLS1_3_TICKET_AGE_TOLERANCE defines the
* maximum difference tolerated for the server to accept the ticket.
* This is not used in TLS 1.2.
* Maximum allowed ticket age difference in milliseconds tolerated between
* server and client. Default value is 6000. This is not used in TLS 1.2.
*
* - The client ticket age is the time difference between the time when the
* client proposes to the server to use the ticket and the time the client
* received the ticket from the server.
* - The server ticket age is the time difference between the time when the
* server receives a proposition from the client to use the ticket and the
* time when the ticket was created by the server.
*
* The ages might be different due to the client and server clocks not running
* at the same pace. The typical accuracy of an RTC crystal is ±100 to ±20 parts
* per million (360 to 72 milliseconds per hour). Default tolerance window is
* 6s, thus in the worst case clients and servers must sync up their system time
* every 6000/360/2~=8 hours.
*
* See section 8.3 of the TLS 1.3 specification(RFC 8446) for more information.
