Say my domain example.com has TTL set to 86400. If i change this through the registrars' panel to 60 when will this change take place? Will it need 86400 seconds ? or will it be instant?
I cant find anything online regarding this.

it can take up to that 86400
but not all recursive dns servers strictly follow ttl values, especially for 60 (expect ttl no lower than 300 real world).
rule of thumb is 48 hours, actual results will greatly vary.
a nice tool to check common public dns resolvers... https://www.whatsmydns.net
For caching DNS servers that cached your domain information immediately before the change is applied it could take up to 86400 seconds for the change to be seen. For DNS server that have never cached your records or have not refreshed their cache since it was last flushed then the change will be seen immediately. DNS servers that have previously cached your information will be somewhere in between 0 and 86400.
