Thanks Eric for the reply.
What is the letter that we need to mention if leasetime is in seconds? Is it
's'?
Also, can you help clarify if we don’t specify the letter and only give number
to leasetime (as below), how does the dnsmasq interpret?
dhcp.@dhcp[0].leasetime='12'
Thanks,
Ravi

The dnsmasq man page states that:
The lease time is in seconds, or minutes (eg 45m) or hours (eg 1h) or
"infinite".
I would assume that odhcpd follows the same convention in order to avoid
playing with conversions.
The source for lease holding for IPv4 appears to be in these two files, not
sure where odhcpd handles IPv6 lease times...
