You can use REGEX_EXTRACT with appropriate pattern and dummy ternary
write dummy jython UDF using java/jython classes for Datetime conversion
You can convert it to unix seconds using "native pig" and sort as integers:
dataWithSeconds = FOREACH dataWithddMMMyyyy GENERATE
ToDate('1970-01-01 00:00:00', 'yyyy-MM-dd HH:mm:ss'))
) as seconds;
ordered = ORDER dataWithSeconds by seconds;
