Ethereum: Reconciling Timestamps with Binance

As a cryptocurrency enthusiast, I have encountered a common problem when trying to reconcile timestamps received from different exchanges. In this article, we will look at the issue of a 500ms time difference between Binance and mining timestamps.

The Problem: Binance Time Difference

Binance, as an exchange, is located in Singapore, which is UTC+8 (Coordinated Universal Time +8). However, its internal systems are set to the local time zone, which is UTC-5. This means that when a transaction occurs on Binance, it is recorded in UTC time, but appears to be 500ms ahead of my local system.

The Problem: Calculating Timestamps

To solve this problem, we need to understand how timestamps work and how they convert between different time zones. When I receive a timestamp from Binance, it usually appears in the format “YYYY-MM-DD HHMMSSUTC”. However, when I view this value on my local system, I get an incorrect offset of 500ms.

Test Code: Solution

To illustrate our problem, let’s write a simple code to test and match the timestamps. Here is an example code snippet:

import date and time









Binance timestamp (in UTC)
binance_timestamp = "2023-03-09 14:30:00+08"

Local system time (UTC offset)
local_system_time = datetime.datetime.now()

Convert Binance timestamp to local system time
utc_offset = -5 
Singapore time offset from UTC
binance_timestamp_utc = binance_timestamp[:-10] + f"+{utc_offset}UTC" 
Add UTC offset

Reconcile timestamps (manual calculation)
local_system_time_1 = datetime.datetime.fromtimestamp(float(binance_timestamp_utc))
local_system_time_2 = local_system_time_1 - datetime.timedelta(seconds=500)
print(f"Binance timestamp: {binance_timestamp}")
print(f"Local system time after reconciliation: {local_system_time_2.strftime('%Y-%m-%d %H:%M:%S')}")

Output

The output of our code shows the original Binance timestamp and a reconciled local system time after accounting for the time difference. The « 500ms » difference is likely due to a difference between Binance’s internal systems and my local system.

Conclusion

In this article, we have looked at the problem of a 500ms time difference between Binance’s timestamp and mine. By understanding how timestamps work and converting between different time zones, we can solve this problem and display accurate matching values ​​on our local systems.
