timeFormat property
The time format that you want to use. Valid values are auto
(case-sensitive), 'timeformat_string',
'epochsecs', or 'epochmillisecs'. It defaults to
10. Using auto recognizes most strings, even some that aren't
supported when you use a time format string.
If your date and time values use formats different from each other, set this
parameter to auto.
Implementation
final String? timeFormat;
