Bug: Incorrect human-readable dates for unix timestamps

[johngribbin]

There seems to be an issue with the conversion of Unix timestamps to human-readable dates in the should_monitor_onchain_funds object returned by the clboss-status call. The now and disable_until values do not seem to correspond correctly with their now_human and disable_until_human counterparts.

Example response:

{
    "status": "ignore",
    "now": 1721640000,
    "now_human": "UTC 2024-07-22 08:29:41.632",
    "disable_until": 1721690000,
    "disable_until_human": "UTC 2024-07-23 00:21:44.860",
    "comment": "`clboss-notice-onchain` to resume managing onchain funds."
}

Issues:

• The now value of 1721640000 converts to UTC time of Mon Jul 22 2024 09:20:00.
• The disable_until value of 1721690000 converts to UTC time of Mon Jul 22 2024 23:13:20.
