Class DateTimeParser

class DateTimeParser

Set format_type_ and parse date/time/timestamp strings into (s,ms,us,ns) since the epoch based on given dim in (0,3,6,9) respectively. Basic idea is to parse given string by matching to formats (“%Y-%m-%d”, “%m/%d/%Y”, …) until a valid parse is found. Save parsed values into a DateTime dt_ struct from which the final epoch-based int64_t value is calculated.
