The rarely mentioned "underside of time" is mentioned in Dark Shadows episode 789.

We lean toward believing this headline.  From The Gateway, 1982.

We encountered and determined the cause of a temporal anomaly in the city of Colorado Springs, Colorado.  The clock in the bedroom of our historic farmhouse lodging displays a frozen time.  As constant investigators of such phenomena, we saw the source of the problem instantly.  Placed right next to the clock is an empty antique birdcage.  That relic is the cause of the clock's inoperability.  An empty cage traditionally symbolizes that something in one's life has escaped; we've all heard that "time flies," and so QED.  Though the cause is simple enough, great mysteries yet abound, for has an old clock in a nearby farmhouse now gained time?  By the way, that slip of paper in the corner of our photo is from a fortune cookie that a stranger gifted me after the Ghost concert we attended (ticket and earplugs also pictured).  The fortune reads, "Do what is right, not what you should."  (And yes, apparently we do take and eat candy from strangers.)

"As we follow the sun -- so follow the seasons."  From Mansfield's 1950 yearbook.

We encountered and determined the cause of a temporal anomaly in the quaint Victorian downtown of Van Buren, Arkansas.  The courthouse clock tower displays two times, only one of which is correct.  As constant investigators of such phenomena, we traced the source of the problem almost immediately.  Directly below the clock face that announced the wrong time, and next to the 1820 schoolhouse where the prominent Freemason Albert Pike first taught, there is a sundial with a broken pointer.  That is the cause of the clock tower's divergence, magnified by the sundial's proximity to one of the oldest standing buildings in Arkansas.  Though the cause is simple enough, great mysteries yet abound, for the nature of time itself is shrouded.  And what, perchance, do the Freemasons have to do with this particular enigma?

"A decrepit clock tower told the Byzantine hours" (Colin Thubron, Night of Fire, 2017).

We encountered a temporal anomaly in the city of brotherly love, Philadelphia, Pennsylvania.  All four sides of the clock tower at St. Paul's Episcopal in Elkins Park told a different, frozen time.  As constant investigators of such phenomena, we carefully searched the church grounds for the source of the problem, sidestepping slippery acorns and dodging a fallen electrical wire by the graveyard.  The entire property is frankly decrepit, with the cemetery unkempt and the overall impression being one of abandonment.  As historic preservationists ourselves, the state of this 163-year-old church was painful, to put it mildly.  With so much disorder, it was difficult to pinpoint a specific cause for the temporal anomaly, so we looked within the name of the church itself.  "St. Paul's Episcopal" is an anagram of "as collapses tip up."  You will no doubt recognize that last phrase as a twist on the great Hermetic axiom, "as above, so below."  The collapsing physical structure of the church, having slowly fallen into decrepitude over time, is reflected above, in the clock tower.  "It is time for Episcopalians across the country to rise up" (Ruy O. Costa).

"What is my real relationship to time?  I experience the near past, the near future, and the very far past; a lot of my soul or psyche seems to be transtemporal … maybe this is why any given present space time seems somehow unreal or delusional to me. I span across and hence beyond it; always have —and the transtemporal is the eternal, the divine, the immortal spirit. How long have I been here, and how many times? Who or what am I, and how old? Reality outside confronts me as a mystery, and so does my own inner identity. The two are fused. Who am I? When is it? Where am I? This sounds like madness. But when I read the Scriptures I find myself in the world which is to me real, and I understand myself. The Bible is a door."

This is the most accurate depiction of how the years are threaded together than we've ever encountered.  From Colorado College's 1912 yearbook.

We encountered and determined the cause of a temporal anomaly in the mountain town of Trinidad, Colorado.  A clock on a funeral parlor displays an incorrect time (four hours early, plus the shadows of the clock's hands depict a bonus time five minutes later).  As constant investigators of such phenomena, we saw the source of the problem with a mere turn of the head.  Directly across the street is an historic gothic house, the Bloom Mansion.  That haunted relic from 1882 is the cause of the funerary clock's error, the effect compounded by the existence of a mini version of the mansion in the form of a Little Free Library (boosting the disruptive signal, as it were, from the macrocosm into the microcosm).  Though the cause is simple enough, great mysteries yet abound, for does a fourth-story widow's walk have the power to disrupt the flow of time?  By the way, as we walked toward the Bloom Mansion on the day of our investigation, our progress was delayed by an improbably long funeral procession that passed in front of us.  As plutocrats of the supernatural, we expected nothing less.

We encountered and determined the cause of a temporal anomaly in the town of Clayton, New Mexico.  A streetside clock displays faces with no hands, bizarrely distorted numbers, as well as incorrect times.  As constant investigators of such phenomena, we diagnosed the source of the problem at a glance.  Directly below the troubled timekeeper is an old sculpture of a dinosaur.  That relic, itself conjuring a past that is forever timeless, is the cause of the pole clock divergence, magnified by the site's proximity to the extinct volcano Capulin.  Though the cause is simple enough, great mysteries yet abound, for precisely how and why do relics have the power to disrupt the flow of time?

We encountered and determined the cause of a temporal anomaly in the scenic city of Chattanooga, Tennessee.  A clock at the old train station (transmogrified into a hotel) displays an incorrect time.  As constant investigators of such phenomena, we saw that the source of the problem was adjacent to the clock.  The famous Chattanooga Choo Choo itself, now permanently inoperative and displayed as a monument, is the cause of the station clock's inaccuracy, the effect being magnified by another nearby train car (converted into an escape room) with the emblazoned words "Can you escape in time?"  Though the cause is simple enough, great mysteries yet abound, for how could a frozen train, formerly famous for keeping to timetables, be so disruptive?
