--retry-max-time

The retry timer is reset before the first transfer attempt. Retries are done as usual (see --retry) as long as the timer has not reached this given limit. Notice that if the timer has not reached the limit, the request is made and while performing, it may take longer than this given time period. To limit a single request's maximum time, use --max-time. Set this option to zero to not timeout retries.

Starting in curl 8.16.0, this option accepts a time as decimal number for parts of seconds. The decimal value needs to be provided using a dot (.) as decimal separator - not the local version even if it might be using another separator.
