datetime_now

PlasmaCalcs.tools.history.datetime_now(*, sep='_', tz='local', timespec='microseconds')

current datetime as string according to user’s computer. Include timezone.

Uses “isoformat”, with “_” separator: YYYY-MM-DD_HH:MM:SS.ssssss+HH:MM

Datetime (timezone-aware) can be recovered via datetime.datetime.fromisoformat(str)

sep: string

separator between date and time. ‘_’ nice when spaces not desireable (e.g. file names).

‘T’ is nice for more universal recognizability; ‘ ‘ too but slightly less universal.

tz: ‘local’, ‘utc’, or datetime.tzinfo object

timezone to convert result to. ‘local’ –> machine’s local timezone.

‘utc’ –> standard/universal time (UTC) (i.e. result will end in +00:00)

timespec: str, probably ‘seconds’ or ‘microseconds’

passed to datetime.isoformat(). ‘microseconds’ –> YYYY-MM-DD_HH:MM:SS.ssssss+HH:MM
