class rfwtools.timestamp.TimestampMapper

Bases: object

Class for mapping timestamps in Tom’s label files to the timestamp with fractional seconds used elsewhere.

__init__()

Methods

__init__()
get_full_timestamp(zone, dt)	Returns the full timestamp based on the supplied zone and timestamp strings.
save_mapper(filename)	Method to save the mapper to pickle file.
update_timestamp_map([mapper, begin, end])	Creates/replaces a nested dict mapping event timestamps without fractional seconds to those with fractions

get_full_timestamp(zone, dt)

Returns the full timestamp based on the supplied zone and timestamp strings. Expects label file format

Parameters:

• zone (str) – The fault event’s zoneformat is CED (e.g., 1L23).

• dt (datetime) – The datetime object containing the truncated time. Typical that microseconds = 0 (Tom’s format).

Returns:

15:30.2”

Return type:

Standard web-based format timestamp string, e.g., “2019-02-01 01

save_mapper(filename)

Method to save the mapper to pickle file. Relative to Config().output_dir, unless path is absolute.

Parameters:

filename (str) – The name of the file. Relative to Config().output_dir unless path is absolute.

Return type:

None

static update_timestamp_map(mapper=None, begin='2018-01-01 00:00:00', end=None)

Creates/replaces a nested dict mapping event timestamps without fractional seconds to those with fractions

Parameters:

• mapper (Optional[Dict[str, Dict[datetime, datetime]]]) – If none, one is generated. Otherwise, the given map replaces the existing one.

• begin (str) – What time should the timestamp mapper begin at if a new one is to be generated

• end (Optional[str]) – What time should the timestamp mapper stop at if a new one is to be generated

Return type:

None
