Add eloop_timeout_remaining and script_envtime so DHCPv4/DHCPv6 dump-lease output can include next_renewal_time, next_rebind_time, and next_expire_time derived from the active eloop timeouts.

Check name Status Explanation Description check The description addresses lease-dump timer output and the new event-loop APIs. It is related to the changeset, although it describes timestamps while the implementation reports remaining seconds. Out of Scope Changes check The changes are limited to DHCP lease reporting, event-loop timeout APIs, and script environment generation. These changes support the stated lease-output objective. Title check The title is related to lease-dump timer output, but it calls the exported values timestamps while the implementation reports remaining seconds.

Explanation
Issue
#714requests historical timestamp information for DHCP and DHCPv6 lease events, including BOUND, RENEW, and REBIND. The change addstime_to_renew,time_to_rebind, andtime_to_expireto dump-lease output. These fields report remaining timeout seconds ornever; they do not record when a lease event occurred.

Explanation
The new eloop timeout APIs and
time_to_*fields implement future renewal, rebind, and expiration countdown reporting. Issue#714requests historical timestamps for DHCP and DHCPv6 lease events. The countdown feature does not implement that requirement and has no necessary connection to event timestamp reporting.

I think we should export any timers in seconds rather than do any formatting. I don't think I like the variable names either. |

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy liftMake lease-time export work for
dhcpcd -U. Both dump entrypoints allocate zeroed protocol states and read saved leases without establishing the live bound state or scheduling lease timeouts. Both new exporters return at their state gates, so a lease dump contains notime_to_*fields. The dump path needs remaining times derived from saved lease data, rather than a lookup of live event-loop timeouts. (raw.githubusercontent.com)

Ensure clang formatting
…nto client_timestamp
If we're processing an already dumped lease file, we don't know how long it has been since the dump occurred, in that case we should just output the total times rather than time remaining. This should be specified in the manual to make clear. |

If it's reading an old lease file, it skips the time_to_. |

Add eloop_timeout_remaining and script_envtime so DHCPv4/DHCPv6
dump-lease output can include next_renewal_time, next_rebind_time,
and next_expire_time derived from the active eloop timeouts.
If using privsep, timestamps are always in UTC, otherwise it will
attempt to print them in local timezone format.
