fromtimestamp()

from datetime import datetime

timestamp = datetime.timestamp(datetime.now())
print("Present Timestamp : ", timestamp)

Present Timestamp :  1568717876.556073

from datetime import datetime

timestamp = datetime.timestamp(datetime.now())
print("Present Timestamp : ", timestamp)

dt = datetime.fromtimestamp(timestamp)
print(dt)

Present Timestamp :  1568717943.760438
2019-09-17 16:29:03.760438

Example 1: Converting a Timestamp to a Readable Date

from datetime import datetime

timestamp = 1609459200  # January 1, 2021
dt = datetime.fromtimestamp(timestamp)

print(dt)  # Output: 2021-01-01 00:00:00

Example 2: Handling Time Zones

from datetime import datetime, timezone

timestamp = 1609459200
dt = datetime.fromtimestamp(timestamp, tz=timezone.utc)

print(dt)  # Output: 2021-01-01 00:00:00+00:00 (UTC)

Example 3: Converting the Current Time to a Timestamp

from datetime import datetime

current_time = datetime.now().timestamp()  # Get current time as timestamp
dt = datetime.fromtimestamp(current_time)

print(dt)  # Output: Current date and time

Example 4: Converting Future Timestamps

from datetime import datetime

future_timestamp = 1798787865  # 2027/01/01 07:17:45
dt = datetime.fromtimestamp(future_timestamp)

print(dt)  # Output: 2027-01-01 12:47:45

Example 5: Handling Timestamps Before Epoch (Negative Timestamps)

negative_timestamp = -123456789
dt = datetime.fromtimestamp(negative_timestamp)

print(dt)  # Output: Date before epoch

OSError: [Errno 22] Invalid argument
