parseTimestampWith

fnSeries parseTimestampWith(Series s, string fmt, bool strict = true)

Parses STRING cells through a strptime-style pattern into DATETIME instants (ADR-2026-10-30-02 D8): the locale-free subset %Y %m %d %H %M %S %f %z %F %T %% (four-digit %Y, two-digit pairs, %f one-to-nine digits, %z Z|z|±HH[:]MM normalising to UTC - the offset shifts the instant, never the stored value). The parse is strict: every token consumes, the whole input must match, defaults are midnight January 1 of the parsed parts (the %F/%T aliases expand). The pattern validates once; null strings stay null; strict failures throw (strict = false nulls them).

Parameters

sthe STRING Series
fmtthe format pattern
strictthrow on parse failures (true) or null them

Returns

the DATETIME Series.

Throws

DataFrameException on an unsupported directive or strict

parse failures.
