epoch to datetime code example

Example 1: python epoch to datetime

>>> datetime.datetime.fromtimestamp(1284286794)
datetime.datetime(2010, 9, 12, 11, 19, 54)

Example 2: Unix time stamp epoch converter

# Unix-time to 
df.Timestamp = pd.to_datetime(df.Timestamp, unit='s')

# Resampling to daily frequency
df.index = df.Timestamp
df = df.resample('D').mean()

# Resampling to monthly frequency
df_month = df.resample('M').mean()

# Resampling to annual frequency
df_year = df.resample('A-DEC').mean()

# Resampling to quarterly frequency
df_Q = df.resample('Q-DEC').mean()

Example 3: epoch

Epoch timestamp is a unit of measurement for time. It is the number of
seconds elapsed since the countdown has started.
