In overall terms:
Code:
- Using date command, convert timestamp_supplied to seconds_since_epoch.
- For each line in log file (while read):
  - Use cut or sed to get date_field.
  - Using date command, convert date_field to seconds_since_epoch.
  - Use test command to determine which seconds_since_epoch is larger.
