Running devnet always results in "isSynced: false"

[IgorKhomenko]

Describe the bug

I'm running a devnet locally via

cargo run --release --bin kaspad -- --devnet --rpclisten=127.0.0.1:16110 --listen=127.0.0.1:16111

Then I'm checking the status on network via https://github.com/imalfect/KaspaNodeMonitor which always says the node is not synced:

[23:16:00 07/23/2024] [ℹ INFO] Kaspa: Node is not synced, waiting for it to sync
[23:16:01 07/23/2024] [✔ LOG] info {
  p2pId: '8bf8254f-37df-46b7-9f00-0a5662ef16ad',
  mempoolSize: '0',
  serverVersion: '0.14.1',
  isUtxoIndexed: false,
  isSynced: false
}

To Reproduce
Steps to reproduce the behavior:

1. clone rusty-kaspa
2. run it via cargo run --release --bin kaspad -- --devnet --rpclisten=127.0.0.1:16110 --listen=127.0.0.1:16111
3. run getInfoRequest rpc to get the node status

Expected behavior
The getInfoRequest rpc to return isSynced: false

Screenshots

Desktop (please complete the following information):

• OS: macOS 14.5 Sonama
• Kaspad version: rusty-kaspa main branch

Additional context
I found the rott cause is laying in is_nearly_synced https://github.com/kaspanet/rusty-kaspa/blob/master/consensus/core/src/config/params.rs#L240

I modified the code to get more logs:

let max_expected_duration_without_blocks_in_milliseconds = self.target_time_per_block * NEW_DIFFICULTY_WINDOW_DURATION / 3; // = DAA duration in milliseconds / bps / 3
let res = unix_now() < sink_timestamp + max_expected_duration_without_blocks_in_milliseconds;

println!("max_expected_duration_without_blocks_in_milliseconds {}", max_expected_duration_without_blocks_in_milliseconds);
println!("sink_timestamp {}", sink_timestamp);
println!("unix_now()  {}", unix_now() );

println!("res {}", res);
            
res

where it's clearly noticed that sink_timestamp has much lover value than unix_now() so the statement let res = unix_now() < sink_timestamp + max_expected_duration_without_blocks_in_milliseconds; can't be true

max_expected_duration_without_blocks_in_milliseconds 880333
sink_timestamp 1231006505000
unix_now()  1721765761634
res false
