That's the question Chicago asks in the song of the same name on their classic 1969 debut album, Chicago Transit Authority (here's a link to the original version before it was shortened for radio play). When it comes to the deadlines for bringing legal claims, not knowing the time will indeed give you "time enough to cry." That's because the law sets deadlines, called statutes of limitation, by which legal claims must be pursued. If those deadlines are missed, the claim can no longer be made in court, no matter how strong the facts and law may be to support it.
The Minnesota Supreme Court ruled this week in Peterson v. City of Minneapolis that the one-year statute of limitations set by the Minnesota Human Rights Act ("MHRA") is suspended while the employer and employee voluntarily engage in an employer's internal dispute resolution process. As a result, employees will now in many cases have additional time to pursue claims under the MHRA.
