Time Stamp eXtensions for Python

This library was created as a response to the known Python datetime standard library flaw that violates ISO 8601. ( Example )

Under the hood, it uses external dateparser library that's fully compatible with ISO 8601, and it simplifies working with date & time stamps.

It also handles properly the Daylight Saving Time (summer time).

Installation

pip pinstall tsx

Usage:

The library is pretty simple, its central class is TS, which inhertis Python builtin float,

so every timestamp in fact is a float representing number of seconds since Epoch.

The TSMsec is the same TS with only difference that it's constructor by default expects msec precision, i.e. number of msecs since epoch,

but internally it will store the same float as number of seconds since Epoch.

TS(ts: Union[int, float, str], prec: Literal["s", "ms"] = "s")`



TSMsec(ts: Union[int, float, str], prec: Literal["s", "ms"] = "ms")

• prec - is precision of the ts argument.

  • If prec=="s" - the ts argument will be interpreted as nr of seconds since epoch,

  • If prec=="ms" - the ts argument will be interpreted as nr of milliseconds since epoch

Example:

ts = TS(ts="1519855200.123856", prec="s")



ts==1519855200.123856

ts.as_iso == '2018-02-28T22:00:00.123856Z'

ts.as_iso_tz(pytz.timezone("Europe/Bucharest"))=='2018-03-01T00:00:00.123856+02:00'



TS("2018-02-28T22:00:00.123Z")

TS("2018-02-28T22:00:00.123")



TS("2018-02-28T22:00:00.123+00:00")

ts = TS.now()



ts.as_sec == 1234567890.123

ts.as_ms == 1234567890123

ts.as_file_date == '20090213'

ts.as_file_ts == '20090213-233130'
