Build, test, and debug regular expressions
This regex validates date-time strings in formats like DD/MM/YYYY HH:MM:SS or DD-MM-YYYY HH:MM:SS. It matches days (00-39), months (00-19), years (1000-2999) separated by slashes or hyphens, followed by time with hours (00-29), minutes (00-59), and seconds (00-59). Useful for parsing and validating timestamp strings with flexible separators.
