Expand description
Error parsing human-friendly duration
Invalid character during parsing
More specifically anything that is not alphanumeric is prohibited
The field is an byte offset of the character in the string.
Non-numeric value where number is expected
This usually means that either time unit is broken into words,
e.g. m sec
instead of msec
, or just number is omitted,
for example 2 hours min
instead of 2 hours 1 min
The field is an byte offset of the errorneous character
in the string.
Fields
Start of the invalid unit inside the original string
End of the invalid unit inside the original string
A number associated with the unit
Unit in the number is not one of allowed units
See documentation of parse_duration
for the list of supported
time units.
The two fields are start and end (exclusive) of the slice from
the original string, containing errorneous value
The numeric value is too large
Usually this means value is too large to be useful. If user writes
data in subsecond units, then the maximum is about 3k years. When
using seconds, or larger units, the limit is even larger.
The value was an empty string (or consists only whitespace)
